I recall the new rule states if you have a ftf on the 2nd shot, after missing the first target, you get to shoot another pair with the first target being a loss, regardless. If you hit the first target and then have a ftf, you get to shoot another pair and that pair is what's scored.
I'm sure I will be corrected if this is not the case.
"A contestant shall be allowed 2 failures to fire, for any reason other
than stated in Paragraph C., 2., above, during each Doubles sub-event
if the Failure to Fire occurs when the contestant attempts to shoot the
first target of a Doubles pair, or when the contestant attempts to shoot
the second target of a Doubles pair after the first target has been fired
at and broken and would have been scored “DEAD”. When the first
target of a Doubles pair is fired at and missed and that target would be
scored “LOST”, and an allowable “Failure to Fire” occurs on the second
target, the shooter may shoot another pair. In such a circumstance the
shooter must shoot at both targets of the repeat pair but the first target
shall be scored “Lost” regardless of the result of the actual shot, the
second target shall be scored as shot. (See exception in VII., E., 11.,
f.) When the first or second allowable Failure to Fire occurs in any
Doubles sub-event, the contestant shall be allowed to call for and fire
at another pair of targets and the result of the shots at the new pair
will be scored in accordance with these Official Rules."
