Egg denting 31 days?

[Syfaii]

I'm about 31 days into incubation 87° f and 81% humidity in noticing some denting is this normal? At this point?

Egg dented quite a bit at the bottom

Are these the first eggs of the season? Is it the gecko's first clutch? Are they soft and dented or hard? Did you candle them, if so is it red or a yellowish color?

Defenetly red and not totally hard but a bit

I know that you are measuring moisture. It could be possible that they are getting dried out which will cause denting.
