Hello, @fynnbruil,
I have just tested the same element on my test site and it works perfectly fine for me, please refer to this screenshot: https://postimg.cc/5YY0DN8v the issue is only on your site, and that might be the third-party plugin conflicting issue, please disable all the third party plugins on your site and check back again, if the issue is resolved, then again you have to activate all the third party plugins one by one and check which one is creating the problem on your site.
Best Regards,
PThemes Team.
