2nd First Stage Feeder dead in 6 months

Weird question, is it just the light that makes those first two feeder slots look like they have yellow gears versus the orange I am used to seeing? Funky.

Anyhow, I don’t have a lot of input as I have had no issues. I do wonder about that spool though and the way its outer edge is thick in some places and thin in others, am I seeing that correctly?
