Damage Control Component

I just added a Damage Control Component to my mod. What it does is it repairs a very small amount of ship tonnage per turn. Its setup so that it requires crew to function, and is only 1 component per ship effective. Problem is, it repairs over 300kt of tonnage each turn. I only made it 20kt at tech level 20 (Max Level). I don't understand why its repairing so much tonnage.
