Well, it depends. If the gun is fairly old, it could be that
the triggering mechanism is worn a bit, and, is not providing the
crisp cutoff necessary for accurate firing.
With me, it is more often because I am pulling the trigger too
slowly. To get a good shot, one has to kind of "flick" the trigger
with a quick pop. A slow squeeze will often get a double fire.
Of course, much of the time, I "bounce fire" by holding
down the trigger and firmly tapping the tip of the gun against the
items to be joined. I find that in THIS case, it works much better if
I aim for a point about 2" past the point I want to nail. Much the
same techniques used for breaking boards with one's bare hands.

It is technique. Mine does the same thing. It has the ability to fire with
the trigger (and nose pressed down) or bump and fire (keep trigger pulled as
you push down the nose). What was happening for me is that I would press
the nose down on the workpiece then pull the trigger. I was pushing hard
enough that after the first fire, the second was a bump fire because the
nose came off the workpiece then back down before I could release the
trigger. My technique for trigger firing is now to press only hard enough
to get the nose in firing position, then pull the trigger. The impact
allows the gun to be pushed off the workpiece hard enough that it is too far
away from the workpiece to bump fire.

Are you using nails recommended by the manufacturer and are you holding the
gun steady against the work to prevent recoil misfire?
