I must have missed seeing this before.
Kobo have a problem on their server. This is creating extra shelves. Some are duplicates of existing shelves. Others are old deleted shelves that have been brought back to life.
As to the space, these shouldn't take much space on the disk. The shelves are just entries in the database on the device. There would have to be millions of shelves for the database to to be big enough to be noticeable.
