Form-Dropdown does not work

Hello,

on all my pages where CRM entries are used, the from-fiter/dropdown at the top of the CRM site does not work.
In the URL I can see that the parameter “form_id” changes, but after the reload the list stays as it was before.
So at the moment it is only possible to access the first contact form, which is very frustrating.

Strangely enough, there are no error logs for the problem….
