Experimental molang features not working in Realms

I have a furniture add-on that utilizes experimental molang features to rotate and merge modular blocks. When testing the add-on in Single Player Survival it is working fine. But when adding the add-on to my Realm it is not working. The modular furniture blocks do not auto rotate or merge together. I have made sure the "Experimental Molang Features" box is checked before uploading my world to Realms. Are the experimental molang features not functioning in Realms currently?
