When I try to batch edit a selected number of participants inside the participants table, e.g. I want to edit a specific attribute of these tokens, the fields "invitation sent","reminder sent" & "completed" are filled out with todays date 00:00 (e.g. 14.02.2024 00:00), although I did not check those boxes or change anything in those fields.

This bugs keeps happening on an irregular basis, approximately every 3rd-4th time I edit some participants with batch edit which makes it a bit hard to track and describe.

When the "completed?" field of a token (with usesleft 1) is filled out with a date, the token becomes invalid, because LimeSurvey thinks it was already used (although "usesleft" is still 1).
This has already given us a few nasty surprises, as numerous tokens became invalid in the middle of the field phase.

In the attached .lsa archive I tried to reproduce the bug. Through the first 3 batch edits the bug did not occur. In round no. 4 the bug occured (tokens 1-7). When you click onto "edit this participant" you can see, that the date is filled out with "14.02.2024 00:00" and usesleft ist still 1.
