Issue with stacking/aligning

Joomla 4; PB Settings for responsive are 1920,1600,1024,800,Between
In PB I´ve loaded a predefined model and set it to "aligned" (horizontally) in all resolutions. In the backend it looks like expected. But in the frontend the colums will be stacked vertically under the resolution of 1600px.
Tried it with selfmade colums (15% / 85%) it also doesn´t behave as expected in the frontend:

Backend, responsive Settings at 1920px:

Frontend above 1600px:

So far it works fine

Backend, responsive Settinggs at 1024px:

Frontend below 1600px:


The orange area comes from row-settings to make it clear:


You can see that the colums are no longer divided 15% / 85%.
Disabeling in the Inspector all five css-rules for "@media" and it will displayed correctly.Can you help please?

it seems that you are loading a moduel of PBCK into a row
the module is OK, but the parent row that loads the module has a stacking setting. Please check that and let me know

That does the trick!
I've searched for hours and haven't seen it. Sorry for taking up your time.
Thank you

great
