I'm not exactly sure how to compose the question I'm trying to ask but can someone explain what has actually happened when a chick "drowns in the egg"? I guess what I'm trying to figure out is, how do they drown in there?

Which humidity levels you normally use? I’m just concern because I’ve lost a hatch due to chicks drowning in the eggs in an forced air incubator, Ive used 55-60% and 65-70% during lockdown. I’ve been searching for articles and infos to help me define it and couldn’t find any straight answer.I drowned most of my first hatch because I used the old school recommended high humidity, 60% to day 18 then 80% (don't do this, it's far too high). The egg shell is porous so water will develop inside the air sac. Chicks pip internally into that sac prior to pipping the shell. The water there drowns them.
I have a Nurture Right 360. days 1-18 the incubator was set at 50 and lockdown at 70. 100% hatch rate. I was reading that was about 5° too high. so i lowered it and out of 9 eggs 5 hatched, not without difficulty, 2 never developed all the way and 2 drowned in the shell and never pipped. So I am going back to the manufacturers instructions of 50° then 70°.Which humidity levels you normally use?
