Confused about a Veiled modifier. Any help understanding this appreciated.

EDIT: hahaha, it's amazing what you can forget after a years absence. I forgot that the trade system doesn't always count double mods as a single modifier, and I somehow glazed over a lot of items with the combination of the two as simply having a combination of two separate mods instead of the one I was looking for.

EDIT2: As if a joke from the universe, I find this mod on a wand first Jun mission I run.

Learning this mod removes the 2h ranged icon from it, removes it from the undiscovered bow options as well. Seems like this mod is completely misrepresented as being possible to put on bows until it is finally found, which I gotta say is pretty disappointing. Curious if there's something I've missed where I shouldn't have expected this thing that said it was a bow mod in two different ways wasn't once you found it.

EDIT3: No one I have asked knows why this mod would show me a bow then not unlock for a bow when unveiled. Could be a bug?

OP:
So there is a modifier in the unknown section of my Veiled list in the bench. In the bench, it reads "Chaos Damage and Chaos Skill Effect Duration" - this modifier is available when filtering by Bows, and has a Bow icon when you hover over it. It reads "two handed ranged" but I am not aware of another type of two handed ranged weapon.

Looking this mod up on poedb:(https://poedb.tw/us/Veiled_modifier#VeiledModifiers:~:text=(60%E2%80%9369)%25%20increased%20Chaos%20Damage%0AChaos,chaos)
Two different tiers. Plenty of other mods on there I'm familiar with with two lines, nothing special here. One line of tags, should be a single mod. Seems to drop unveiled on 1h weapons primarily. Lots of chaos, plus skill effect duration. Looks great.

...but where is it? Not like, "how do I unveil items" but...
I can't find it on any weapons, I can't find the mod itself on the trade site to search for, let alone any items with it, and even google searches return nebulous answers as to whether or not it 1, exists or 2, can appear on bows. In every site I can find the mod on, it always comes with a 0 weight on bows....but it is most certainly and absolutely right there waiting for me grayed out looking quite attractive for my build inside the actual game itself, surrounded in bow icons, undiscovered.

What gives?
