Hello, @jimmy,
1- Actually, when I check your issue there is nothing it is working fine I have tested it on your site as you can see in the video: https://www.veed.io/view/9e03a236-1ee5-40d8-8cbf-f2b5f0661366?sharingWidget=true please check back to your issue after clearing the browser cache. I hope you will never face any issues.
2- Yes, you can add the image there by going on the header builder and setting the HTML block element in the header bottom then setting the image in it. See the image for a better reference: https://postimg.cc/qz2BbQSK
