optimize mac storage option keeps turning itself off

Hello,

I have been having a problem with icloud drive where when I enable Optimized storage in system preferences, then exit and re-enter icloud settings, optimized storage is now unchecked. My computer is running out of storage so I would like this feature to be working.

Thanks for your help!

Here is a google drive link to a screen recording: https://drive.google.com/file/d/1Ebi5XFBc5FKyAArwBuL4virNwW5Guyj3/view
