Hi Biljana,

sorry to hear that you are experiencing this problem. I gave a look at what happens behind the scenes and found that apparently 38 items show the same problem. The list of item IDs is:

"7737190, 7737298, 7737456, 7737707, 7737780, 7737816, 7737822, 7737833, 7737973, 7738042, 7738071, 7738135, 7738149, 7738188, 7738360, 7738410, 7738416, 7738598, 7738926, 7738939, 7738980, 7739051, 7739134, 7739234, 7739235, 7739315, 7739367, 7739466, 7739602, 7739640, 7739793, 7739878, 7739922, 7740023, 7740043, 7740054, 7740440, 7740588" (they all belong to the WOK 7/30/2012 series of sources)

Can you confirm that the items you found belong to the list? (this way I'll know I am looking at the right problem).

As this is quite certainly a bug (and a very rare one), I will need to investigate in detail and find a way to make sure that it won't happen again. I will, of course, fix your own situation, but would like to investigate the issue first, if that's all right with you.

Could you please try to describe (with as much detail as possible) what you did while duplicate checking? I'm interested to know if you used the "reset" functions, if you manually added items to groups, if you manually created groups and if/when you have used the "mark automatically" routine(s).
I hope this information will be enough for me to find the cause all this. I'm very sorry for the trouble.

Many thanks for letting us know,

Sergio

Hi again,

I've given a first look and couldn't find anything that seems to cause the problem. Yet, it happened, so the cause must be there, somewhere. I will look into this systematically early next week, thanks for your uderstanding! Please do let me know if you wish me to fix your shaded problem (the effect, not yet the cause), I can do this pretty quickly and I will probably not lose too much useful information. In the mean time, if you can have a look at the involved groups (in duplicate checking, advanced tab, click "find", paste the list of IDs I've provided, and click GO), you may remember what history/procedure they may have in common. For example, if all of them have been manually created, this would be a useful hint for me. In all cases, please don't act on these groups, otherwise you'll risk to confuse me even more.

Will report back, as soon as possible, hopefully with news about the fix.

Best wishes,

Sergio

Hi Biljana,

I think I've found what caused your issue: identified and fixed it so that it won't happen again.

The details: the problem showed up when adding items from one group into another. This is done through the "Manual / Advanced" tab, click on "Add Group" button. This allows to type in the ID of a group so to add the members from it on the currently selected group. The bug shows up if the "source" group (the group that corresponds to the indicated ID) contains the master item of the currently selected group. Under these circumstances, the current master was incorrectly marked as a duplicate (of itself) and removed from the active list of items in the review. This didn't show up within the duplicate-checking interface because it was not supposed to happen!

Can you confirm that the situation explained above is what probably happened within your own review? If so, I will fix your items and let you go on with your work. If not, it means that I've fixed a previously unknown bug, and that I still need to find the one that troubles you...

Thanks again,

Sergio

Dear Biljana,

Sorry for the delay! I have re-instated the affected items, so all should be good for you now, and yes, of course you can resume your work as normal.

I have also updated your account expiration date, just four days as a symbolic thank you for your patience.
Thank you once more for spotting this and allowing me to fully investigate it. I wish to sincerely apologise for the inconvenience.
Please feel free to get back in touch if you'll need any further assistance, we're here to help.

Best wishes,
Sergio
