I don't know if this is your problem, but I do notice that dragon disciple claws often create false readings in the character sheet, though in my experience attacks still do the right amount of damage. Go into the PRC menu on the radial, then into "select primary natural weapon" and select none. That always clears up the character sheet for armed characters. Conceivably that might solve your problem, but be warned that if that is the solution, you need to repreat the process each time you rest or level up, as the dragon claws re-equip by default in such circumstances.
