The denting is probably from low humidity. It kinda bites that you don't know how long they have been in there. It looks like she's in a tank? One way to retain humidity good in tanks is covering most of the screen lid with saran wrap.
I would be careful about abruptly changing the humidity levels though. I would try to do it gradually. I am sure that someone that is more experienced with maternal incubation can chime in though.
But never spray or douse the eggs themselves with water!
