Multicam not displaying all angles/cameras putting on same track

Hi getting to grips with Multicam.

I have 2 go pro cameras and another camera that recorded audio. i want to use the angles of the go pro and sound off the other cam

I have selected all the clips, right clicked and created a new multicam.

When it displays on the timeline the 2 different go pros angles appear as one track together even though they are different shots/angles.

I have tried 3 times to select again in the hope of getting a 3rd track but it's not having it. Strangely when i try to create another version it takes no time at all and there is no processing time, like the first time

I have renamed the clips and still no joy. Help !

Many thanks
