NSSA doesn't allow type 5's to be propagated into the area. Question i have
is, is your R5 OSPF NSSA router an ABR or truly an ASBR?. If its an ASBR
meaning you have done some sort of redistribution into OSPF on R5, then
those redistributed routes will show as type 5 in non nssa and type 7 in
NSSA area provided you haven't manually defined "no redistribution" on the
NSSA area.
On the other hand, if your R5 is just an NSSA ABR between two OSPF areas and
the Acual ASBR is another router, then what you're seeing is expected.
