How are you playing back your bag file? What command are you using? My first guess is that you aren't using --clock (or maybe it's that you are). Then you send a set_pose command, and the filter resets itself, but the filter _will not_ allow any measurements that are older than your set_pose time stamp, so all the bagged messages are ignored.
In any case, the time stamp in your set_pose publication needs to be based on the same clock as the bag.
