Module Banner messed up mobile layout

I have the problem on 3 mobile device browsers:
Firefox, Chrome and Safari see attachment. 1 screen with all 3 browsers

Which browser do you use?

With my android smartphone and with pc all work best with edge,firefox, firefox nightly, chrome.
I (only) can reproduce this issue on safari on apple.
The jem_banner normally is not thought for the content, after all for module positions. Perhaps this has to do with this. But I will test more.
EDIT:
on chrome on apple, I can reproduce too! It seems this is a problem on apple!:sick:

Problem solved
I uninstalled the template and reinstalled the template. This solved the problem
