It _might_ be:

- An incorrectly configured route-map
- An incorrectly configured access-list used in the route-map
- A bug in IOS (probably unlikely, but who knows :-])

The problem is that no one can make any guesses, since you didn't
include any information to help determine the cause. And no example of
the not-filtered prefix seen from the neighbor.
