Feedback module has different design settings in the embed than the Roadmap and Changelog

I really love the Featurebase embed for our website.

I just seem to have a tiny coloring bug which is a big problem right now:

As you can see in the screenshot below, the embedded Feedback module is making the header have white background.

The Roadmap and Changelog behave differently though and adjust the background to the same grey as well:

Am I overseeing some styling options or why is the Feedback Module behaving this way?

It would be great if the background were grey here too, otherwise it looks super unprofessional on our website and I can’t add it.

Thanks so much in advance! :)
