We’ve discovered the issue. Looks like James gave you the solution, but didn’t make it clear where the layout needs to be changed.
Open your PumpNoPercent template, and select the triangle. Notice the red arrows – these are directions where you have Anchored layout. You need to use Relative layout for the triangle to do what you want.
Now select the circle. Again, notice the red arrows. The circle also needs to have relative layout.
When you change the layout for both items in the template, the triangle starts to rotate like you would expect.
