Well not exactly Karl, Once a tour leg is flown it is completed as far as the tour is concerned and it won't be generated more than one for a pilot. And once filed it will generate the following leg. (Which can't be reversed even if I reject your flight).
Now a couple of options here.
If this was your 1st leg of the tour, I could remove you from that tour which clears your records/flights off that tour, then you could re-join and start over.. but your are too far into Tour 3 to clear you off to start this tour all over (in other words there is no way to "un-do" a tour leg). Once a tour leg is flown/filed it can't be removed or regenerated - BUT there is another option to re-fly the same route as that tour 3, leg 9.
In the tour details doc, you will see that the tour leg 9 route is also flight MFCT00025-6A0.
MFCT00025-6A0 VFR Nichin Cove (AK62) to North Whale (96Z) (Via Coffman Cove (KCC) - 42.1 nm - 3500'
So you can bid/fly flight # MFCT00025-6A0 and cover the same route as that tour 3, leg 9.
Also your bad leg 9 once filed, still generates leg 10 of that tour. So you can jump right to leg 10 if you want but if you want to fly the complete route of tour 3, leg 9, just fly flight MFCT00025-6A0 and you will finish at the correct location for leg 10 of that tour. (Every tour and every tour leg has a corresponding MFC flight schedcule that can be flown).
A bit messed up in the logic but this is best we can do on short notice!.
