Incorrect information in ride summary

I cycled Box Hill last week and set a 30 day PR going up. When I saw the ride summary at the end of the ride, under achievements it listed a PR on Fox Hill. I thought maybe I had just seen it incorrectly.

Then yesterday I rode Box Hill again, again setting a 30 day PR, and the ride summary again showed me a PR on Fox Hill.

I think something has gone wrong in the identification of the hills in the ride summary.
