Inventory Slots Are Missing.

Hi there, Mojang developers.
Recently, I discovered a bug on 1.1 beta update.
My inventory slots are missing and I need to exit the map and re-enter back in order to see my inventory slots back.

My device for MCPE Pocket Edition Beta 1.1 -
Sony Xperia XA Dual

The proof is in the attachment below.
Thank you for watching this bug report.
