Pillagers spawn in caves!!!

Seriously 😡

When I triggered a raid on my artificial village the villagers spawn down in caves and the baddest thing is that there ia a laaaaarge cave system below my living area I'm still exploring it means really large!!! So it makes me impossible to complete even a raid I tried 3 times but all the villagers do spawn in caves so please fix this, means why there is a need of pillagers in cave they're attacking village not caves so why they need to go there like they're hiding or something what's the reason for spawning them in a cave so please fix and please totally remove pillagers from spawning in cave.... It's not needed!!!!
