I may have just answered my own question.
After using another camera to record the flash sequence i can see that the FS3 is actually firing 2 flashes, just too fast for me to see with the naked eye.
The substrobe is being triggered on the first flash, then obviously not on the second flash. There is nothing in the menus i can find for turning this second flash off on the camera.
Now to try and find out how to either
1. pull the flash apart and find a way to delay the trigger by a tiny amount, so that although triggered off that first flash it will actually fire in time for the second. captured at 30fps i had 1 white out frame, one normal frame, one not so whited out frame, then blacked out for several frames.
2. rip out the guts of the flash and replace with a land flash using the water proof housing.
oh well it WAS a very cheap flash, so i may as well play!
