[Bug Report] Garmin Fenix 5s Plus data field selection error

For context, I have software version 15.20 on the Fenix 5s Plus. 

I was out for an mtb ride, with a power meter linked to my watch. I wanted to change my data screen to show 10s power vs 3s power.
When doing this, I selected data screens, selected the data field I wanted to change. I selected “Power Fields” followed by “Power.” But once I selected “Power” I was immediately sent back to the “Power Fields.” It was like it wouldn’t let me select a the field of choice and the computer automatically selected the first option within the sub category. This seems to only be an issue on this data selection. I have had no issues with other sports such as running, swimming, etc. 

I have tried a hard reset with no luck.
