Actions and Stuff Resolution Slider Issue on Realms

The resolution slider on Actions and Stuff does not work on realms. The slider itself says that a change has been made but nothing changes in game. The slider works in a regular world as intended but not on a realm. I would like to be able to have vanilla textures with the new animations the pack provides but this bug forces me to have all or nothing unfortunately. From what I have heard, this bug also affects other packs with a similar slider mechanic.
