The Scrollbar in the browser shifts the side and effects the slidebar for example

Design help Layout & Design

Hello everybody,
when i publish my side, the added scrollbar (vertical) shifts and effects the layout. The Slidebar is effected up to the 3rd backgroundpicture. Also when i click on my topics the shifting appears. Is there a possibility to fix that?

In the preview in webflow everything is good. Also when i change the window size in the browser slightly, it is gone. Weird!

Really glad about an answer.
