Poe Trade Forbidden Flesh Cobalt Jewel and Forbidden Flame Crimson Jewel bugged in STD?

Hey

I'm trying to find/buy

Forbidden Flame Crimson Jewel
Forbidden Flesh Cobalt Jewel

With Allocates Avatar of the Slaughter if you have the matching modifier on Forbidden Flesh

But even tho I can find Forbidden Flame, Crimson Jewel there is absolutely 0 For Flesh. Not that it's 0 now, it's 0 EVER, like in past too. 0 sales in total.

Is this like a super nonexisting rare jewel, or does it not show up in Poe trade? I saw something similar with a few other items in past.

Is it a bug?

Regards
Dariusz

I'm hopeless at searching, thank you!
