Cannot set workout metrics for hiking in workout application on Apple Watch Series 3

When I use the workout app for hiking it only shows me the following metrics on the watch face during the workout: duration, active calories, total calories, and heart rate.

I want it to show me additional metrics relevant to hiking such as distance and elevation gain. I attempt to add the desired metrics [Watch app --> Workout app --> workout view --> hiking], and my iPhone screen looks as follows:

But when I save my metric preferences and close out of the app, these metrics preferences disappear, and when I use hiking in my workout app it goes back to only showing duration, active calories, total calories, and heart rate. And when I go back to the metrics preferences screen, it looks as if I never saved my metrics preferences:

I can easily switch the metrics for other exercises without a problem at all. But it doesn't seem to work for hiking, which is pretty aggravating because hiking is one of the primary exercises that I do and one of the main reasons I purchased my Apple Watch. Any suggestions?
