Lioneye's Vision Crusader Plate no Pierce support?

So.. I wanted to use this armor in prophecy league, but when I searched it in PoE trade, the lvl 15 pierce support property on this armour is missing. I didnt find anything in patch notes or gamepedia.. is it a bug, or am I missing something?

If it's a mod that doesn't appear on other items, as is the case with a lot of Uniques, the owner of poe.trade has to add them manually into his system so some of them can be missing on the website.

It should be as intended in-game, as it has no legacy versions or anything like that.

Well, when you try to search for it in standard, there are some armors with pierce and some without it, so it doesnt seem to be a problem with poe.trade visibility of the mod.

Edit: So I contacted on of the sellers and mod is there.. so just weird poe.trade bug.
