CSS only showing if I go directly to URL vs navigating to page?

Site URL: https://www.wethepeoplesbefore.org/join-us

My css is only showing up on my "Join Us" page if I go directly to the URL (https://www.wethepeoplesbefore.org/join-us) vs. navigating to the Join Us page through the menu from the other pages.

The CSS is to collapse, frame in a thin box(only css that works from either entry method), and style my Info and FAQ text so it's not an intense scroll session. Even though I land on the same URL in the end, i'm not sure why navigating into the page through other pages on the site makes it function differently. Does this have a fix? Please advise 🙂 

I'm thinking the curse of Ajax Loading strikes again! Try turning off Ajax Loading to see if the problem goes away.

Please note that turning off Ajax Loading will affect the performance of your site. Ajax Loading is designed to increase the loading speed of your site after it first loads.

You have to decide whether the custom code you are trying to use is worth turning off Ajax Loading.

paul2009 has a great article on the ins and outs of Ajax Loading. Please see Why does Squarespace code only work on refresh?

That was it! Thanks for the share, I'll keep this in mind for future builds! 

My Countdown clock on the homepage still disappears when it wants... but the rest of the pages are cooperating, so I'm not going to push my luck. hahaha. 🤣

Thanks again @creedon
