JQL stopped working as expected 'fixVersion WAS IN (XX) ON -1W'

[Dmytro G]

I have 2 filters:

1. Find items removed from release during last week:
   project = TNC AND type = Story and fixVersion WAS IN (25cw36) ON -1w and (fixVersion != 25CW36 or fixVersion is empty) order by priority desc

2. Find items added to the release during last week:
   project = TNC AND type = Story and fixVersion = 25CW36 and fixVersion WAS NOT IN (25cw36) ON -1w order by priority desc

#2 works as expected, while #1 displays work items that I have removed from 25CW36 way before -1w, for example (queried on July 11, 2025):

Hi Dmytro,

For number 1 if you ran it yesterday, it would have been off by one day. Try -2w just for fun to see if it shows up.
