My 1.0.5 beta update is not reading any world saves and will not generate a new world

Upon opening Minecraft PE my world saves are not showing and when I try to generate a new random world I get a notification that the world cannot be loaded. I am using a ZTE Z981. I backed up my world saves and uninstalled and reinstalled but that did not fix the issue

To fix this issue (of missing saves), go to settings, profile, and change save location to external.
