As per the paper book on page 59 first paragraph...
Toughness...can only be increased above your base stamina rank using advantages and powers, not by direct spending of power points.
I made a automaton construct and much to my surprise, Hero Lab put the arrows next to toughness and indeed let me spend power points to increase my toughness directly. This seems to be in direct contrast with the rules. I even started over and did nothing but select automaton and go directly to the abilities tab, and it still let me spend power points. The other heros I have made (ie. non constructs) can NOT buy increased toughness with power points.
Now I'm really new to M&M, and I bought Hero Lab to help decrease my learning curve. So it is highly possible that HL is right and I am wrong, I just want some clarification please, because it seems like a bug in HL.
