Hello @ljackl
Hope you are well!
This looks like there is another plugin or theme affecting the appearance. Please run a quick check for a conflict:
Deactivate all other plugins and see if the issue is gone. If the appearance is still broken, please switch to a default theme, like Twenty Ninteen. If everything is well, activate one plugin at a time to find the one that causes this.
Follow the steps from the flowchart:

Please have a site’s backup before proceeding with this test, just in case if something will go wrong, you can always restore it. If you have a staging site, please run this test there.
Let us know how it went!
Cheers,
Nastia
