Gated products in ungated brands

Hello, I’m ungated in Nike and have been selling it for a couple months, yet every now and then I stumble on a Nike product that says I need to be ungated to sell it. Also had a Nike shirt that I sent to Amazon and once in warehouse I received a notice saying I couldn’t sell it and I need to be ungated. I sent my original invoice I used to get ungated but no luck. Has anyone gone through something similar? Any help is greatly appreciated.
