Stick Nav Bar Page Builder

Hello,

I am trying to add a sticky nav bar to one my pages, and used WP Sticky Pro plugin for the nav bar. The sticky nav bar works, but when you reload the page, the nav bar disappears and doesn’t format correctly. I contacted their theme support and they said it could be page builder compatibility issue. Do you know how I might be able to fix this? The link to it is here: https://centerforaddictionstudies.com/certification-requirements/us-substance-abuse-certification/massachusetts-ladc-substance-abuse-certification-test-2_jf

If there isn’t a way to fix it, what would you suggest I do to create a sticky nav bar that is compatible with your theme?

Thanks,
Tyler
