This sounds like a problem I had! Look at which routers are actually puting
the routes into OSPF and compare this to your RID in your distance
statement. I had fun figuring this one out!!

This is odd, I have an ACL to the distance command under OSPF on R5 and R6
(doing mutual redist. on OSPF /EIGRP):
R2's OSPF RID is 192.168.2.2
router ospf 1
distance 171 192.168.2.2 0.0.0.0 10
access-list 10 permit 192.168.8.8
access-list 10 permit 10.8.1.0 0.0.0.255 access-list 10 permit 10.7.1.0
0.0.0.255 access-list 10 permit 10.7.2.0 0.0.0.255 access-list 10 permit
172.30.80.0 0.0.0.31
I clear the route table on R5 and the routes are correct:
r5#si ei | i EX
D EX 192.168.8.8 [170/307200] via 172.30.200.7, 00:00:21, Ethernet0

When I clear the route table on R6, R5's then installs the OSPF routes:
(after clear ip ro * on R6)
23:37:52: RT: no routes to 172.30.40.0
23:37:53: RT: closer admin distance for 10.8.1.0, flushing 1 routes

How can that be? Shouldn't the ditance command adhere permanently?
