Private match issues xbox

Having issues with xbox one private matches. When a player joins the host and wishes to be terminators, they are unable to swap to a different squad as the game changes them to tyrranid, resulting in two teams of genestealers.

A work around is to have the host always be space marines, but that's where it gets interesting. When the game starts, regardless of which chapter is chosen the genestealer player will have a random chapter with random squad members spawn in. When the players commence with their turns the game doesn't seem to sync properly resulting in essentially two separate games happening simultaneously. When me and my friend played his squad were static on my screen for several turns as he moved through the map on his xbox.

I really love this game and am super excited to play with other people when it works
