Problem with Aberrant Fossil Crafting

Hello, I think there might be an issue with rolling "60% chance for Poisons inflicted with this Weapon to deal 100% more damage".

I buy a Trisula Dagger from the market with elder influence, item level 86, and the mod, "60% chance for Poisons inflicted with this Weapon to deal 100% more damage".

I roll 35 aberrant fossils on this dagger using primitive chaotic resonators. The mod never shows up again. Am I this unlucky or is there something wrong with the dagger or the mod?

I also rolled roughly 100 orbs of alteration and the bleeding version of the mod did show up, but no poison. Sorry if I am missing something here.

Guess I'm just unlucky. I got two more fossils dropped from a weird spot and I rolled the mod on the second one.

Also just realized I posted this in the wrong place. Going full tilt today. I'm so sorry
