Memory of Arbiter Judgement bugged

Can’t buy the memory of arbiter’s judgement despite meeting both requirements which is having Revered with the Ascended and unlocking Runecarving.

Each time i try purchasing it, i just get told “that item is locked” and i cannot buy it.

Please note that talking with the Runecarver, The game tells me that i do meet the requirements to buy it.

I submitted a ticket and got no response except “Ask the forums” while actually asking the forums in a different post got completely ignored. Hopefully this one gets more attention.

Looks like this poster figured it out:
