Background: We are running two copies of the Xbox-Bedrock edition of MC on the same home network and have them both open to friends. No matter which of the two someone out side of the network tries to connect to the they always end up in just one of the two servers. 

To reproduce: Run up two copies behind same router. try to connect to one of the worlds, check you get in the right one. If its the right one disconnect and try the other server. You end up going to the first one instead. Joining Via friends page via Xbox Live.

Expected: You get into the World of the player you are trying to join not another persons world on that same LAN.
