always booting snapshot...

Hi, recently i booted a snapshot and wanted to revert the state. I did some commands the commandline suggested me and it worked, but now the system is booted always from that snapshot… I dont know why…


mount | grep snap
/dev/mapper/system-root on / type btrfs (rw,relatime,space_cache,subvolid=573,subvol=/@/.snapshots/259/snapshot)
/dev/mapper/system-root on /.snapshots type btrfs (rw,relatime,space_cache,subvolid=258,subvol=/@/.snapshots)

Is this normal or should i change that??
