Issue using global search

when I use the search bar to search ‘GLOBAL ’ across all locations, tagspaces 5.6.2 pro seems to go through all the folders and shows (based on the glimps I see when I press search’ ) all or at least some of the files found, but then they all found files dissapear instantly within the second, as if nothing was found.
When I search location per location for the same search criteria, search works fine.
Is there already a version somewhere where this bug? is fixed?

I can not reproduce this issue in the latest 5.7.10 version. Can you please try to reproduce it there?
