Scavs don't spawn

Hello, I have a problem and it is that scavs do not spawn, bot players spawn normally and sometimes on the maps there are only them, sometimes two or three scavs will appear but nothing more even when I set the number of AI to horde nothing happens only when I press the scav wars button then sometimes thirty or forty of them will appear in one place but they kill each other. When I play scav sometimes I am the only scav in the game. I tried different options in the mods and nothing helped. I use google translator so sorry if something doesn't make sense
