When finished I umounted /mnt/temp (the top-level) and then my 3 subvolumes was unmounted and a cannot mount them at the same mountpoints again... No errors and it says that it is not mounted when trying to umount them. So it seems they don't get mounted at all and without throwing an error

Given those symptoms (mount doesn't report errors, but no mount
happens), I would guess that your problem is with systemd. It has a
bug where it sometimes unmounts things immediately after you've
mounted them.
