But you shouldn’t add all those masters just because of a warning in a test tool. You font will work just fine without the. The file will be much bigger for no reason.
Some vendors have overly strict requirement and those are build into some test profiles. That’s why I asked for what profile you were using.
The second warning is actually something else. It has to do with the order of name particles. Not sure why they like it the other way around? Maybe because of your axis order?
