Can't edit screen

I downloaded this AIA file to make my quiz app.quizmyedit.aia.zip (101.2 KB)

In here I can see this screen..

But when I go to edit this screen in design section there are no any elements related to this screen.

AAnyone can help me..

See below Vertical Arrangement 5

If so, it will be in invisible, make sure each arrangement is visible is true. also, if you set all to visible then it will create a problem so handle carefully

Okay thank you @Anu10 ..
