A library file keeps switching off

Opposite to this thread (Turned-off asset libraries keep reappearing), we have at least 2 asset libraries that keep switching themselves off (in the Resources of the Admin settings), which makes them not be automatically added to any new files. We have a very small number of admins and we’ve checked with everyone, no one has intentionally switched them off.

Has anyone experienced similar behavior or have any tips on how to solve this?
It doesn’t seem to show up in the Activity tracker or switching them doesn’t trigger events, is this the case?
