Site can't be displayed if there are too many hidden objects above

Hello,

Im struggling with something that happens to me every now and then.

When I’m in the Avia Builder I like to build all Elements in groups for each device.
Example: First I build all the Elements for Desktop, then I build all Elements for Tablet and in the end I build mobile.

Problem:
The Last Device will never be displayed in the Browser. When I test on mobile desvivces, the Page is blank.
When I switch tablet to the end in Avia Builder, then tablet will show a blank page.

It seems as if browsers don’t like too many hidden Elements above the element that should be displayed??

PLEASE HELP! :)
