Hi Robert Pflaum,
Please check which FTM module you are using?

From the above picture, you can find FTM0 and FTM1 only have 2 channels, so, if you want to use 6 FTM channels, you need to select the FTM2 module.
Wish it helps you!
If you still have question, please let me know!
Have a great day,
Kerry
