“Window Shopping” not registering objective after completing first time

The Gullcrest Village challenge “Window Shopping” requires that you; grind a rail gap, complete manual distance of 10m, flip trick the stair gap and complete a best sequence score of 750.

Once I complete the grind the gap objective it no longer registers completing the objective in additional attempts when trying to complete all the tasks in one sequence.

This results in me having to end the challenge and retry it after each time I successfully grind the gap but fail other objectives in the sequence.
