Can't display Airtable data in Webflow dashboard – attributes disappear after rescan

Guys, I really hope someone can help me. I’ve been working on this all day and just can’t figure it out. It’s probably just a small detail I’m overlooking.

I want to display user data from Airtable in Webflow (in a dashboard). There is a dashboard page, but each logged-in user should only see their own data. The data is matched using the user’s CMS ID, which comes from Memberstack after login. In Wized, I can also see the attributes—they load briefly and are visible after a rescan, but then disappear right away. I really hope someone can help me because I have no idea where the error might be. Thanks, Roman
