Strange grey icon pops up every click/tap action in my prototype

Hey there~
I was really proud of this prototype I made recently… added in a fake loading event that triggered a new page load and everything. Worked great when I was testing it locally, but when I uploaded it to the cloud, each tap/click interaction now triggers this weird grey box so you have to click twice to do the action.

Whatever this is, also bugged out my “loading animation” and it seems the interactions won’t trigger properly anymore. Thoughts?
