I think usual way is to create partition table with single partition
(and create LUKS on that partition)
IIRC device manager will not complain if there is a partition table.

So you destroy LUKS header or keyslots by mkfs? This is wrong, don't do it.
It is just pure luck if it works. (It was actually kind of a bug in mkfs that it
did not destroy LUKS signature properly.)
