Site logo header stretched in mobile mode

Hi all,

I’m using Themify Ultra and Elementor? Strange I know. Anyways, when in mobile mode, the header is enlarged and the logo blown up, but as you scroll down it goes back to normal. Unsure which theme is causing the issue, but most editing has been done via Themify.

How would I get it back to displaying in normal size? Many thanks for any future help.
