How many batches of eggs have you tried to hatch? Are the quail housed outside in freezing temps?
I have hatched some bobs in the past. I would have to look up the exact temps again. I don't remember if my incubator can do 99.5, so I probably had set at 99 or 100 instead. I read a few places saying humidity should be around 80%, but I can tell you that I did not have the humidity that high at all. Probably between 30 and 40 percent. Then increased a little bit on lock down.
I would save your eggs for a week or two, tilt them once or twice a day in an egg carton ( I never thought to do this in the past) Then incubate the larger batch. Only open to adjust temps / humidity or candle the eggs. (Did you candle the eggs at all? Did you notice any blood vessels? ) Then at day 21 remove or stop turning eggs. Lock down, and wait for hatch. The membranes are much thicker and they shrink wrap very easily. Try not to open the incubator during lockdown.
How many males to females do you have? Do they have a nice large white markings on face or half white half brown? or still light? Possible male is not old enough yet?
