Now reading this third thread, I understand what your issue is.
You CREATED your template using the standard/historical/East Asian composer. You CANNOT change it to the MENA one. You must recreate your template using the MENA composer. That's why you've been having problems. Even though you've changed your document composer, the specific type layer that you are using is already tagged as East Asian and as a result, you're automatically reset to the East Asian composer any time you attempt to edit it.
As I wrote in another thread on this topic, unless you are using advanced Japanese or Chinese typography, set the composer to MENA and do ALL your work there. It will be easier for you since that composer supports all languages.
And, again, had all this info been in a single thread, the solution would have been both easy to see and quick to obtain.
