Issue Regarding Dynamic Content Slot in E-Mail Builder

My Mautic version is: 4.4.9
My PHP version is: 7.4.33
My Database type and version is: MySQL 5.7.41

The dynamic Content Slot does not respect filter settings and always shows the default block in the Email.

The field “Permission” is a custom field of Type “Select”:

Configuring a simple string filter, like “Email == …” works.

So it seems to an issue with the Select Type custom field.
Is this a known Issue
Or should this be created as Github Issue?

Yes, plz.
Also mention there which emai lbuilder you are using and which template.
