device and OS first: Volla Phone X on UT 24.04-1.3 stable.

I probably have a simple little problem (I had this before upgrading the OS so it's not due to the OS version):
When tapping on the menu in the upper left in the file manager you get to "Places". I've got a file there (instead of the "Music"-folder) I want to remove since it doesn't belong there. How do I get rid of that file that is unfortunately named "."? I can't see any sub-menu or similar to do so.

Earlier, after e.g. a folder has been selected, there was a button to add it to "Places" to get faster access. I still see this on my other device. This button also has gone on my Volla X. Therefore, I can't add "Music" to "Places" again. How could I correct this? Should I reinstall the file manager? How to do so, since it's a pre-installed app?

Thank you!
