Tap to navigate doesn't work, only makes the page scroll down?

Hello,

I’m currently trying to create a set of frames/pages where you scroll down to pick a big category, then scroll down to pick a small category, and so on and so forth.

Problem is: A button that I set as “tap to navigate” to another frame only scrolls the page down when tapped in prototype mode. It’s as if the button works as “page down” button.
I’m uploading the button in question here. Also willing to share my figma link if interested.
Thank you!
