Layout Grid moves over or under

[mccs]

I have a problem with layout grids. (Wysiwyg Web Builder V15.4)

I have inserted several layout grids one below the other. Worked fine.
Then changed colors etc in title layout grid 1 (with menu in it).
Copied the changed title layout grid to other pages.
Now just trouble.

In the browser happens:.
1. All layout grids are displayed. The later ones (i.e. layout grid 2, 3, 4 etc.) only if there is still space at the buttom of the window.
The bottom is cut off as normal.
When scrolling up the page, layout grid 2 moves over layout grid 1.
Layout Grid 3 later moves under Layout Grid 2.

What do I have to set where so that the layout grids do not slide under or above other layout grids, but keep rather normally
be displayed one after the other?

Are not all settings adopted in the copy style and paste style? For later: which ones are not?
Thank you!

To be able to help you, I need a copy of your project file (wbs) so I can see all your settings.
I do not need the complete project, only a small demo with one page and the relevant objects.
