Thank you so much!
It was indeed 'Activate on Scroll Element Transitions.'
I changed the Offset Desktop to 50, and everything is working perfectly again. In my opinion, it even looks better.
The issue was probably due to the fact that the footer followed shortly after, causing that section to load...
(Sorry, I didn’t want to include the link yet because it’s a new project that hasn’t been made official.)
Thanks for your help!!
