I know for a fact that you have gone deeper under the hood of Kinetic than I ever have, so there is not much direct help I can offer.
But remember Kinetic can save files as PTN which can be opened directly within Project5 (if you have it or it probably can be found somewhere at a real steal even though it is no longer being developed). Project5 probably can handle more easily whatever Kinetic is failing to for you.
Otherwise, you may have to export the wave files from within Kinetic to avoid the 2 channels of roadblock that seems needless but immovable.
Best wishes on breaking through it!!!
