Realms resource pack resolution slider not working

I’m have been trying to add actions and stuff to my realm and it will not let me change the resolution of actions and stuff from the default 16x to 32x. Whenever you join the world after switching it to 32x, the changes do not apply and revert back to default, I’ve had this happen with many other packs on realm and I have decided to report this because it has been a bug for many years.
