Content ‘jumps up’ when use logo instead of site identity

Hi, I'm trying to use a custom logo instead of the site identity (name and/or tag line) but no matter what size logo I create and upload, all pages and posts shift upwards. When I click the "display site title and tagline' option in customizer -- site idenity, pages and posts render fine. It's just when I try to use a logo. I have made a few CSS customizations via customizer, so I'm not sure if there is something there causing the problem. Anyone have any idea how I can use a custom logo and not have pages shift / jump up ? My site: thewaryworker.com I loaded an old logo for reference. Thank you, Kat
