Trying to purchase a cosmetic, says I’m not eligible

Hi, I own the physical copy of D4 for the PS5 and purchased the expansion a few weeks ago. I have leveled the Spiritborn to 60 paragon 272. Have 2800 platinum and wish to purchase the spirit of death skin for the spiritborn. Through the online shop it says I’m not eligible to purchase, through the ingame shop it directs me to purchase the expansion (again).
