Still not earning skill points for RTG

Going on junior year and I’ve only been able to upgrade my 5 star RB to low 80’s in spite leveling up multiple times and supposedly earning skill points but they show up silver/gray and don’t accumulate towards my actual skill points. Only way I’ve earned skill points is through training and thus a very low and slow progression that’s kinda killed the game mode for me. Is there a reason training and game XP/leveling up has not resulted in skill points?
