Header gets cut off

I created a custom header for my site. On the index page, it shows up just fine, but on the other pages, the bottom is cut off.

If I go back into the customizer, take off the header, and then put it back, it is fine on all of the pages, but as soon as I do anything else on any of the pages it gets cut off again on all of the pages.

I made some alterations to the argent theme for the background colour, text colour, and bullets… but when I checked the css in dreamweaver it doesn’t show any problems.

The site is creataholic.ca

I would be so appreciative of any help you can offer. I’m a newbie… this is my first site ever.

Thanks.
