Please Explain Community Folder Installation Status

I have just 3 add-ons in my FS 2024 Community folder. For each of them I get the following indications (see attached picture):
Installed
N/A
So I’m happy to know they are installed but what does the N/A mean? Not Available? Not Applicable?

I’ve never seen anything from Sim Rate Selector on screen during flight. My model matching is non-existent as far as I can tell and my Bell 407 still won’t cold start.
Therefore I assume N/A is a bad thing. What do I have to do to make these add-ons work, if possible?

I don’t have any idea but some of my Installed have an indicator of the disk size used and some indicate N/A.
