Interactions playing differently after first use?

I have created a pop-up Survey window which is playing correctly the first time round but on trying it again after that the animation doesn’t work properly missing the ‘survey’ screen that’s held in an iframe is missing.

Scroll to near the bottom of page and click ‘Take Survey’ button to see the animated pop-up window.

Here’s the link to the Designer: Webflow - UK Medical Freedom Alliance
