you are right about those two fields missing is the reason why the template is rejected. Unfortunately have at least one of those fields is a must have for NTA to be able to pair flows with information from NPM.
You can try to ask Extreme Networks if they can add those fields in some of future versions of ExtremeXOS...

This has now been resolved,
Although I have been unable to find any documented fix for this in the EXOS release notes it works on EXOS 15.3 but didn't on 12.6 or 15.2.
