No PMC spawning on Labs

I have found settings that make enough PMCs spawn on other maps in my opinion, but for some reason when I go into labs it's nothing but raiders, no PMCs in sight anywhere. Not sure how to fix it.

It turns out it's very random, theres been multiple labs raids where there have been no PMCs, however literally right after I made this post I went into a couple raids and there was a bunch of PMCs, they usually dont have that great of gear though and I have like advanced pmc loadouts mod, not sure if that's what it's called or not but they are there. But once again I go in sometimes still and there is none. Do you know a way to make PMCs stronger against scavs? they are usually just dead anytime they run into them
