Missing edit pencil and preferences in workout to change view

I have an Apple series 3 watch and trying to change the workout view on an indoor cycle workout to include the heart rate zones graph view but unable to as I don’t have the preferences option when I press the 3 dots on the workout. when I press the 3 dots, the only options I have are shown in the attached picture with no ability to scroll up, down or either side for additional options.

My watch is up to date with software and I have already tried resetting it as well as unpairing and pairing again with my phone. Any help would be appreciated.
