As you can see in the screenshot https://prnt.sc/yYn_O72PGOyq from top to bottom I have defined the section in the Layout Florist with 2 x headings (100% Width), 3 x Image Layouts (each 33,333% Width) and another 2 x Image Layouts (each 50% Width). If i delete the last not needed Image Layouts, all Addons where put in one row and get the Width 16,666%. This change is present in "Laptop", "Tablet Landscape" and "Tablet Portrait" view but not in "Mobil Landscape" and "Mobil Portrait" view.

This bug is very time consuming because if i want to change the layout only a little bit i have to change all affected values again and maybe i dont remember all values defined earlier. :-(
