One-time license fee for play on account’s designated primary PS4™ system and other PS4™ systems when signed in with that account.

Quote:
You can download and play this content on the main PS5 console associated with your account (through the “Console Sharing and Offline Play” setting) and on any other PS5 consoles when you login with your same account.

Sooooo... Probably just some glitch with the online store? Are you able to browse the store via the console? That might more reliably take you to the right version.
