postgres cascade weird behaviour

Hi

I have table A with pk that is being referenced by 5 other tables as foreign key
I have put all those tables reference to be ON DELETE CASCADE
However for some reason when I tried to delete one of the row in table A, out of 5 tables, 1 of them didn't actually get deleted
but the transaction is completed successfully
so I ended up with a table that has a foreign key referenced to a row that doesn't exist anymore in table A

postgres is not reporting any error message, so I have no idea how to supply more information to this problem

any idea?

Thanks
