[6.9.0-beta25] Mover doesn't see cache

Background:  Just installed 6.9b25 from stable 8.3.  I have never had cache setup before, just used the cache drive for docjer and appdata etc.  Mover has never been used

With 6.9 I setup 2 cache pools.  System which will have appdata & docker.img,  and cache pool of 2 SDD which I intend to use as a proper cache drive.  I have set these up and they appear to work ok

When I go to scheduled tasks / mover, I see the following:

I have setup shares to use the cache drive, appdata which is Prefer and a couple of other shares as yes

I've tried stopping and starting the array and restarting the server, which doesn't change anything.  Any ideas of what the problem could be?

Diagnostics attached
