I'm no longer sure where you are, sorry..
I think we discussed that you need to enable ATU age interrupts in order
to keep the ATU in sync with the bridge FDB? Which means either to
delete the locked FDB entries from the bridge when they age out in the
ATU, or to keep refreshing locked ATU entries.
So it seems that you're doing neither of those 2 things if you end up
with bridge FDB entries which are no longer in the ATU.
