Need help with license issue

Hi, I need help with a licence issue for Detroit: Become Human on my PlayStation account.
I currently have access to the Standard Edition, which appears to be through PlayStation Plus. However, I want to purchase the Digital Deluxe Edition because I specifically want the PSN avatars and other Deluxe content.
The problem is that when I open the Digital Deluxe Edition, the Store says “You already own another edition” and marks the Deluxe Edition as unavailable for purchase. At the same time, the Store still allows me to buy the Standard Edition separately.
