Autofill ruins the form

Hello everyone, I’m encountering a really weird and nerve wrecking problem with a form on my site, and I can’t seem to figure out what is causing this problem, would really appreciate if someone would help with a solution !

What happens is that the form works 100% fine every time I go through it selecting the options and filling the fields manually, except when I choose to use Autofill on my phone for name & email and not fill it myself. Soon as i do that the form goes crazy and i have something like what you see on the screenshot, a weird screen where it gets stuck in between two slides and the form stops working.
Thank you!
