Same thing has happened to me. Not sure how to fix it other than reseting my puzzle rating completely
Cannot change rating range in custom puzzles
Mine is stuck on 200. It won't let me change it. Chess.com will not respond to inquiry,
You are just a mere paying customer, why would they bother to respond to your inquiry? That would be at odds with their time-tested strategy of disregarding complains of their customers, pretending everything's fine as long as possible, waiting for problems to blow over and only acknowledging something is wrong when the outcry is impossible to ignore.
Way easier to manage your expectations, once you understand this.
The issue is still there. Anyone who represents chess.com wants to give an update? Is it looked into? Investigated? Payed any attention to at all?
It is about puzzles, one of the basic payed for features of this site.
Yes, I cleared the cache (I really don't have to, but I did), it did not help. It made it even worse, because after clearing the cache it went to under 200 range (which is probably the default) and now I cannot change it at all, which makes custom puzzles completely useless.
