Problem with NSSA

Good evening,

Giving the folowing topology in Packet Tracer 6.3

OSPF NSSA

https://www.dropbox.com/home?preview=topology+ospf-eigrp.PNG

I have Area 30 with R2, R3, R4 and R5 configured with area 30 as nssa. Between R5(ABR) and R3 there is an ethernet link and the others are connected with serial. Area 0 receives the external and intra-area routes but R3 and R4 do not have the N type(LSA Type 7) routes in the routing table as they should, although they have E type routes(LSA Type 5) that are forbidden to circulate through the NSSA, right? 

R3# O E2 10.10.0.0/30 [110/180] via 10.10.0.18, 00:16:52, GigabitEthernet0/1

R3# O E2 10.10.0.4/30 [110/180] via 10.10.0.18, 00:16:52, GigabitEthernet0/1

And also they are routing towards R5 - so R5 is advertising LSAs Type 5 into the NSSA. Please help

Also onr the link between R5 and R3 R5 is DR and R3 is BDR.

Thank you.

Reformulating my question:

How is the DR,BDR and having a multiacces link affect the NSSA and the advertisement of Tpe 5 LSAs? What can I do to have working functionality?

Thank you.
