That's a fair number of fertile eggs to be dying out of a clutch this small. What is your temp when measured at the surface of the egg, and if not, what are your current temps and where are the tips of the measuring devices. Have your temp measurement instruments been calibrated or checked. I only ask because some of these have been found to be faulty or out of calibration.

Full air saturation is not a bad thing as long as the eggs aren't setting on an overly wet substrate. The ambient air humidity in the cages of my maternally incubating pythons holds between 90% and 95% during the entire incubation period. This would put the intra-coil humidity somewhere between 95% and 100%. If your box interior temp can be kept close to the temps of the egg container, you will not see the large degree of condensation. Also, as Tom mentioned, a very slight amount of ventilation will help as well, as it seems your egg containers appear very tight. Cutting back on the moisture of your substrates as you did will also help.
