Editing FT critters

[Mulligun]

I'm experimenting with editing FT critters ent's files using FT Tools. There is one strange thing that I can't understand. Let me explain on example.
I open e.g. deathclaw_01.ent file. I would like to chane DR (damage resistance) param value for the critter. On the character stat's screen the "Damage Res." position says 15% ...

...while on the left entity's stats panel in "Attributes->Derived"

and "Modifiers->Derivied"

both normalResist fields says "0".

And there is my question. Why there are 15% in char screen when there are zero's in normalResist fields? Where that 15% came from?
Is there any possibility to change this value?

Thanks for help

Hardcoded racial base levels iirc.

Yep.
Mutants get 25% normal resist, DC get 15% and humanoid robots - 50%.
Other base bonuses vary with race as well.
