Button Link Not Working

Hello there,

I have been using your landing page builder and am almost done, but am having trouble with connecting a third party link to a button in the builder. The landing page can be found here:

nomatic.digital/marketing

I would like the buttons to connect to a third party quiz system here:

https://nomaticdigital.outgrow.us/nomaticmarketing

but when I try to click on the button it ends up sending me to a 404 error located here:

https://www.nomatic.digital/marketing/&aiEnableCheckShortcode=true?popb_pID=37234&popb_track_url=https%3A%2F%2Fnomaticdigital.outgrow.us%2Fnomaticmarketing

Would you happen to be able to tell me why this is happening and how to fix it?
