Hi everyone, My Sram GX Cassette is making a weird scratching noise in all gears, except for the 50 tooth. All of my limits and adjustments are set correctly and it shifts great. It just makes a very annoying scratching noise. Its not the derailleur or anything else. I am wondering if it is because I have a Sram NX Chain? My Drivetrain setup is: Sram NX Eagle Derailleur, GX Shifter, GX Cassette, NX Chain, and NX Dub crankset and bottom bracket.
Please help for I am at a loss. Thanks.

Put a 12 spd chain on. You might have 11 spd. This is wider. The 50t clears all other gear interfaces so it wont make the noise

It has a 12 speed NX chain on it. And yep I figured that's why it didn't make the noise in the 50t.
