No, that's not bug, that's feature. If fstrim frees space, then you have
discard enabled on host (in VM config).
You need to enable discard for guest filesystems on mount (usually in
/etc/fstab), or just put fstrim to crontab.

But when this is not enbaled by default in Proxmox it sounds like a "bug"

Problem is that I have in general no access to mount options inside Proxmox.
Fstrim is working for me at the moment. But this cant be a working solution.

This means that this 94.22% was once used. LVM knows when guest uses
block first time, and allocates it at this omoment, but does not knows
when it is freed in guest. You need to enable discard both in disk
config on host and on filesystem in guest (via mount option of FS, or
regulary run fstrim or its analog in your guest OS) to free space on
host's LVM level.
