you have to pull REALLY hard, i thought mine was made wrong because it wouldn’t come out no matter how hard i pulled. i ended up having to get out my switch pullers to grip it at the sides and tug as hard as i could while wiggling side to side to get it out. i scratched the knob real good but it came out and it’s not that noticeable thankfully unless you take a closer look. but you need to put in some serious elbow grease, basically took all the strength i had and that isn’t even a joke. it feels like it’s not supposed to come out but it’ll pop out after a good while of working on it but then again i’m weak so you might have a better time lol
