You have to make sure when you order the double crankset that the spline type matches- both 24mm and both the rounded spine profile.
I"m still scratching my head over which pieces you are fitting, especially since the tandem crankset axle lengths are different than the regular double crankset axle lengths. Maybe when you get some time to lay it all out for me/us, I'd see the light
