Duplicate mobile headings

Hi guys,

I’m new to Webflow and so far I love it, although it’s a bit more difficult than I expected. I found an awesome template which I started to optimize and one of the things I struggle with is an error I can’t figure out: all the headings on mobile are duplicated or even tripled (one layer on top of the other, please see screenshot). This error is only visible on the live mobile version and not on the dashboard preview window.

Help much appreciated, thank you in advance!
