Square D QO breaker

If you take a look at the breaker I attached, it mentions 75degree only for #6-#2, would that mean I can't use Romex (nm cable) larger than #8 considering nm must be used at 60 degrees?

It does seem like bad wording, but I think the intent is that #8 would be 60 degrees aluminum, or 75 degrees copper #6 to #2 rating is 75 degrees for all.
