Seafile-data directory significantly larger after upgrading docker image

So I just upgraded my seafile server for the first time (from 7.05 to latest 7.1) and while it went relatively smoothly I have noticed that my seafile-data directory is now 3 times larger than before (from 5GB to 15GB).

Is this normal? Is there any clean-up I’ve got to do after updating? I ran the garbage collection script but didn’t make a difference.
