[6.9.0RC2] Mover & multiple caches -> file exists

I had a share that was set to cache prefer on cache nr 2.

I want to get rid of cache 2 to replace hdd's with ssd's.

So I changed the setting to cache yes on cache nr 1.

When I started mover it wanted to move the files on cache nr 2 but it said "file exists": move: move_object: /mnt/cache2/xxx.yyy File exists
When I set it to cache yes on cache nr 2 and restarted mover, it started working again.
