Select box bug (MCPE 1.1 Beta)

In beta I have weird bug with select boxes such like changing gamemode from menu and others. When I want to change something with select boxes, I choose, what I want to change, but it stays open on screen and I'm taping anywhere, but it doesn't closes, only restart of MCPE works. But thanks.

Device: Lenovo VIBE P1m using MIUI 8 Custom ROM
