We are experiencing issues with security levels. We have 4 different security levels defined, but users are not able to see all there tickets in boards.
I'm part of all 4 security levels but even I can only see tickets of 2 levels. We noticed this in boards and therefore started checking the board filters and column issue status mapping. The column mapping is ok because we see the ticket if we change the security level.
When checking the filters we noticed the same issue in the new issue search function but not in the old issue search function, in the old search I can see all tickets.

233 results with the old search:

It seems that the boards are using the new search algorithm and that there is something wrong with that.
