Rollershutter bugged in MainUI


I am using the rollershutter Widget on different pages.
On my PC they all look good(on fullscreen). On my mobile devices when putting two vertical rollershutters next to each other they get squished slightly smaller and with three of them next to each other the buttons are overlapping(see image).
This problem is proportional to the width of the brwoser window. Is there a fix for this?
