All the classes I bought after level 50 are not receiveing class points

Title says it all. I don't know exactly after wich point this started but I noticed it when I tried to gain class points to Chaos Slayer and gained none in most of the monsters, I know there are bots to do this and they work but I'd like to rank the classes as I use them through the quests.
PS: This happens to every class I've got after level 50

/join batllegrounde. The monsters there gives me many cp. My LDK got rank 10 after I used 1 hour cp boost and 20 mins cp boost. I'm level 65 btw.

once you reach a certain level killing high level monsters will no longer grant you xp or cp. The best places to train are timespace or if your level 45+ then shadowrealm. Both these area will give you xp and cp
