Jetstream designs LSGG - FS2020 to 2024?

I currently own the Jetstream designs LSGG (Geneva) airport in MSFS 2020, and was trying to see if I could install it in 2024 as well. On the marketplace page in 2024, it shows as compatible, however if I go to my library to install, it says ‘not available’, and not entirely sure what that means. Screenshots attached, can anyone help.
