This is an Outgoing issue and I just already Giving up on Themler!!! I'm tyred to WASTE MY TIME ON THIS!!!
I know you have Themler for Drupal developed by a third-party developer, But can you please ask him to get his head out of ass and FIX THIS!!!

Every time When I change Custom Template which is Set to be Customized all the rest Templates such as Default or Blog is also changed! and if - somehow I manage to make them be different - when navigating from page to page the WRONG TEMPLATE selected, but by refreshing the page the template works fine! I had the same issue before years ago and it's still was not fixed.
Regardless of what I'm doing - setting each of the templates to be NOT DEFAULT but Customized - they are all linked one or other way to each other and there is no way to make ACTUAL CUSTOM TEMPLATE FOR EACH NODE TYPE!

sorry for my speech, but I'm really tired and waste my time on this....

If your developer does not do the job, then do not Offer the Drupal version at all - as it's not Working as it meant to be.
It would be much faster to do everything with the CSS Styles manually then trying to do this over Themler - once again WASTE OF TIME.
aaaaa!!!A!aaa!!!!! a!!!! l have almost smashed my screen trying to style node types....................................
