Bug: overwrite from Live

There´s a new bug in Overwrite Collection from Live. I did this (as always), and suddenly I have, above my 13 datarows, 15 empty ones, only holding an ID.
Until there´s a fix: how do I delete those empty rows?

It could happen if the live database collection had those 15 empty items before you clicked to sync.
Meantime, you can right click on the a row number and click to delete.

Hi, Shay, thanks. But no, the Live Collection did not have then (nor now) the extra rows. They all had the same date/timestamp, the date/time I selected the Overwrite Collection From Live.
Anyway, I did find the Delete Row function, but, my mistake, because it looked like nothing was happening (all rows are empty and look the same), I thought Delete didn´t work. On closer inspection (remebering the first part of the ID), I noticed that a row was deleted.
If I have some time left then I will try to repeat it and see if I can document it better.
Thanks for your help.
