Hi Jan,
It appears that the containers for the widgets are not stacking properly when loaded in mobile view. You'll need to edit the mobile layout so that they are stacked on top of one another instead of pushed into the same space.
From what I can tell, it looks like you're using Showit as your site editor? If so, there should be an image of a phone in the bottom left of the page when editing your site that will let you readjust elements for mobile. You may also want to look into "Mobile Layout Assistance" which is a feature they offer to automatically readjust the layout.
