What's is going wrong here? Are the templates in the database but were not read from the filesystem? What steps do I have to perform to make the new site-templates become effective?

When you set a template in Postorius, the template is stored in the database and an entry is made in Mailman core's template table with a uri to the Postorius API to get the template. As long as this entry is there, that's the template you get.

Delete the template from Postorius and you will get the template from the file system.
