My experience is I put bags in all of the 9 slots, I tried putting returnable items in different bags and told it to return the items to the bank, and they did. Is it possible to turn off feedme and autoforage (if running) to rule these out?
::EDIT:: Ok so I got to looking at the common denominator here...that Mystical Bolt...Somehow it got put into my Equipment Keyring.
Once I took it out of the equipment keyring TCN stopped trying to grab that bag slot entirely.
I turned off feedme, it didn't help. I didn't have autoforage going either.
Here is what I'm getting in the MQ console.

My bank slots aren't full...also here is an annotated version that explains what I'm witnessing during that process.
[TCSNeXt] Moving to bank to store items
(Actually moves to bank and opens banker)
[TCSNeXt] [Storing:] (1) (Mystical Bolt) ID: (95070)
(Picks up the bag in slot 9 (inv slot 31))
[TCSNeXt] Your bank slots are full!
(Claims bank is full...which yes it is full of bags, but not all of those bags have items in them)
[TCSNeXt] [Pausing] [No Bank Slots Available]
For shits and giggles I took an empty bag out of the bank and bagged it in inventory...this is the result of that.

(Moved to bank as expected)
[TCSNeXt] [Storing:] (1) (Mystical Bolt) ID: (95070)
(Picked up bag slot 9...placed it into bank)
[TCSNeXt] Your bank slots are full!
(Picked up the item that dropped into bag slot 9 (inv slot 31) in this case the Diminished Gem of the Acrobat that was just made)
(Again claims bank is full even though there are open bag slots in bank)
