Staff page with Set library. The problem is in upper right.
There was no problem in previous versions. Now, after installing version 21.05, the library name is displayed incorrectly in the upper right (HTML class logged-in-branch-name). It should be correct as it is in the Set library: Bédiho knihovna.
