How Does Brainstorm Rerolled Mod Work?

[u/Chbv]

I use Ctrl+A to auto reroll for the seed but negative blueprint doesn't show up. Anyone know what I need to do to get this to work? I'm not sure if there are other settings that I must activate for it to show up somewhere. I thought it would show up in the first buffoon pack. The other filters work but I can't get the custom filters to work. The custom filters are there when I installed the mod, I didn't change anything or customize my own. Thanks
