Insufficient mixing, or improper proportions are frequent causes of
epoxy not curing.  Contaminants can also cause failure to
cure.  Given the spotty nature of the problem it is probably
caused by not enough mixing or contamination.  The epoxy itself
can be the cause of the contamination, in the form of a cloudy
material on the surface (amine blush).

Can you remove the soft spots and re-apply epoxy?  If so
this is the approach I would take.
