Behringer DDX3216 - Problems with boot

[Phoebus1966]

There is no styles drop down at the bottom.
I did not tap on any delete function.
I use Samsung's own browser on a Samsung J530F.
Try an Android smartphone yourself to experience the problem: Tap pencil, scroll to text frame, tap on text frame to change its contents. Poof! All disappears. I repeat: I do not tap on any delete function. No way.
I can mail you a video capture of the process.

I am in Mobile style, not Full Site style. But that's not a 'drop down' menu.

In Full Site style everything is too small of course, that is why there is the Mobile style.
