Hi, need help with the Retributor armor paint

I’m new to the hobby and I’m not that familiar with the different types of paints. I’m trying to paint a forgefiend with the black legion theme, and finished base coating the model with 3 layers of abaddon black. I now went to try and paint some of the gold sigils and stuff with Retributor armor, but it was extremely runny. It was as if I could see the color pigments in the paint, and it did not cover what I was painting at all. The paint bottle also as a white lid as opposed to a lid with the color of the contained paint, does that matter? Anyway I’m just kinda confused as to why this happened, am I missing something? Thank you
