My first guess is that you are entering an invalid value for a field, such as a number greater than 1.0 for Thermal Absorptance which expects a fractional value. We generally follow the EnergyPlus IDD for what values are acceptable.
Validation doesn't happen right away, so a bad value may appear to stick, but then will revert to old value if you leave the object and come back. We have an issue filed for this. Ideally it will never let you type an out of range value.
