When going offline. Im stuck as alex. Cant play as steve.

When playing offline. The characters disappear, and turns into alex. I should be able to play as steve, even when im offline. I know this as a fact because ive been able to play as alex for the last decade offline.im playing on pocket edition. I already checked for updates and its updated to the lastest version.it doesnt make since not being able to play as steve (the default character). Even if im offline.
