Actions & Stuff Resolution slider not working on Realms

I've seen other posts with people having the same problem, and I just want to summarize the issue and to put my experience out there. I got actions & stuff and when I applied to my realm, it applies both animations and the texture pack. Trying to use the resolution setting that activates vanilla (32x) and custom mode (64x) doesn't seem to work. I would like to put it on at least 32x mode or 64x mode, but no matter what setting it's on, it's still on the 16x mode that activates both texture pack and animations. If anyone has found a solution to run a realm using only the animations without the texture pack (32x mode) please let me know!!

Edit: im using version 1.0.4. also, I'm not very technical, but The problem seems to be that the resolution setting does not save its place. Once you leave the menu, leaving the Realms Edit page reverts it to 16x mode.
