Imperial Editions 8 skins, which weapons? I don't see any on Zealot

I was wondering if people could let me know which weapons the 8 skins are for. I am trying to make sure I even have them. (I 100% own the pack, I have the armor etc)

On my zealot I have a variety of weapons but none with skins. I noticed this because my Twitch drops aren’t showing up either.

I know it works on the semi auto lasrifles and the chainsword.

Hope that helps.
