My friend fixed this by making sure there were 0 spaces in the name he used.

This is a post for my friend who's encountering this bug, but he's been levelling and is around level 30 now but can't seem to create a legacy. When he makes a legacy it only shows achievements and when he closes it and opens it again it asks him to name his legacy once more. I don't know how to fix this, but has anyone else encountered the same issue and knows how to fix it?
