It's unlikely that you will be able to get the twist out, and keep it out
over time, by applying heat since the pre-preg skins are already heat-set
during manufacture. The skins are vacuum formed using preimpregnated glass
(or carbon fiber - depending on your kit) at a temperature that precludes
any subsequent, lasting, shape adjustment using heat. Application of enough
heat to adjust the flap shape could screw up the strength properties of
finished part - and it's most likely that within some time (a few months to
a year maybe) the part will go back to it's original shape.

You may possibly have to cut the trailing edge apart, and reach in to loosen
some of the ribs, reapply adhesive and rejig the flap to the correct
alignment.

There may be other ways to attack the problem and maybe the factory can
help. Just be aware that the reason these airplanes are so strong is that
the parts, under stress, retain their strength and shape.
