You most likely have some old snapshots that weren't updated. As you already went to the back-end, can you see any output with the command: btrfs subvolume list -s /data (replace data with the name of your volume)? Alternatively, you can download the logs and look into btrfs.log

The location to store the snapshots was changed at some point. If your snapshots weren't updated to the new path for some reason, the GUI can't display them (so you can't delete them from the GUI), but as they're still present in the volume, they still take space and the btrfs statistics still show them.
