PS5: Jeweller not combining gems correctly

As title. Yesterday I tried to enhance a Diamond and it only gave me the option to upgrade to a Skull. I thought it may be because I had other items in the inventory at the same time, so tried it with just three Chipped Rubies and that only gives the option to upgrade to an emerald. I’m not sure if it worked correctly on the first early access day as I had all gems in my bag at the time so didn’t notice.

Since I never saw skulls, perhaps this is not D3 related? DI or D4 is only 2 characters.

Ignore wrong part of forum, should be for D4.
