No, it's not particularly normal.  One end of a connection closing the
connection should result in that end sending a FIN.  The only reason I
can think that this wouldn't happen is if the FIN is waiting behind some
other data that have to be sent in that direction.

That's fine and to be expected.  The pcb may still be used in the other
direction.
