Nav menu pushes the content down

Hi,

I’m kinda new to Webflow, and I am currently learning a bit, anyway I can. Anyways, I came across a problem where whenever I open my Nav menu while in Landscape and Portrait mode for phone the Menu seems to push down the whole content on the page just a bit and it looks like it kinda jitters every time it opens, and closes. It moves just a couple of pixels but it is really annoying. I spent 3 days trying to figure it out so I have to ask here.

If you have any kind of advice it would be much appreciated.

Thanks.

I have found out that the action of clicking the hamburger menu icon, in preview, which shows the drop down menu is the trigger for this occurrence.
