I have exactly the same problem. Only with Seblod and T4 template. Not sure if it's a Seblod or T4 issue.
I have written on the Joomlart forum and the developer wants to log into a live site to see the issue and try to sove it, but I am on localhost. If you are working on a site accessible from the internet, you may want to allow the T4 developer access to your site so they can check it.
