OTMater audit flags errors in Glyphs naming policy

Hi there,
Is there any guide out there for font naming policies / best naming practisings using Glyphs? (for non-linking families).
I thought I was doing it right but OTMaster flags some of the fields as having mistakes. The fonts seem to install and display well in the menus, BTW.

There is the Naming Table spec:

Many designers insist on keeping the ‘Regular’, and to my knowledge, it does not matter IRL, especially if you are not linking families. You can override it with a Name Table Entry parameter.
