Ranked can't fill squad

Summary

I’m playing with a friend, my friend is playing on PC and I’m playing on Xbox Series X.
After inviting my friend and selecting Ranked Battle Royale mode and I select squad it doesn’t let me fill, the option is greyed out. This issue is only prevalent when ranked is selected.

Other ranked game modes don’t have this issue such as og ranked game mode.
