/var/lib/openhab/persistence ownership changes to root:root

Hello,
I am running Openhabian 3.2.0 and something with the file permissions/ownership is messed up. Ownership of

/var/lib/openhab/persistence

changes to root:root after every reboot.

Any idea how I can fix this?
Thanks!

I assume that you use ZRAM.
What is the permission of /opt/zram/persistence.bind/

Ownership of that folder is root:root. I am not using ZRAM (I use an SSD and no microSD card).
I fixed the issue (hopefully) by executing “Fix permissions” in openhabian-config.
Edit: actually, the “fix permissions” changed the ownership of the persistence folder to openhab:openhabian. That resulted in error messages due to lack of access to this folder.
