auto-sweeper not sweeping from conveyor receptacle

I have this same problem.  It works for one of my conveyor setups - moving coal into my generators, but won't load into a storage area. 

The priorities on all the structures are the same, therefore there is no reason to transfer anything.
 

wow, thanks, didn't realise that sweepers relied on priorities.  Newby with the update.

This is unintuitive behaviour and a perceived bug. I hope this issue is revisited.
