A RR needs to advertise the best path to each RR client, that’s its job.
If it should also send the best-external (which would be, by definition,
not the overall best path) to the clients, you need to use add-path as you
need to advertise more than one path. Have you enabled both? can you share
IIRC this is the same on XR, you also need to enable add-path on the RR..
