[Please advise] Setting up a funnel on carrd

Hello Fellow hackers!

I have a landing page for a project built on Carrd, but the analytics does not seem to be working well (2nd stage of the funnel is displayed more times than a button leading to it is clicked :/ ) Any best practices on how to monitor funnel stages for a LP built on Carrd?

I am looking to monitor a funnel:

Visit page from PPC > Click a button > Fill the form > See confirmation page

Shouldn't be difficult, right? But it seems like I am getting nonsense in Google Analytics :/ Any advice welcomed

Best,
