I routinely use 2 entrances, one is the normal entrance on the bottom of the
hive and the second is in the first super above the queen excluder.  The
"super entrance" is a 3/4 inch hole and I put a small landing board below
the entrance.  The field bees seem to like the going straight to the super
and not having to fight the queen excluder.

the space and the normal entrance to fly in and out.  Is this a problem?
Should we seal the space?
