AI denoise feature not showing up?

So, I know the AI denoise feature has been around for a while, but it's not until now that I've found a use for it. However, when I naviagte to the details tab the AI denoise isn't there at all (see screenshot). My friend has the same macbook as me and it shows up for him, and my lightroom is up to date. Is there anything I need to do to enable the feature or something?
