I don't see any wrong with your configuration but the config can be simpler.
For me, I won't use prefix list to deny the route but let the statement
"route-map OSPF->RIP deny 20" to filter the routes.
Pleae provide the show ip route in the rip & full configuration of the
router to let us to see which router redistribute the ospf route into rip
domain
