"Time in other locations" feature of unity is buggy

[Shane O'Connell]

The Unity time display thing lets users show times for multiple timezones if you go to the time settings and check "Time in other locations". However it seems to be buggy, here are the steps to reproduce:

1. Turn on "Time in other locations" in Time & Date settings, click "Choose Locations", remove UTC and add a city. (I added Edmonton, Canada)
2. On the calendar dropdown, you see two times listed at the bottom, your current location and the timezone you just added. There's a dot next to the current location, seeming to indicate you can switch between them, so click the timezone you just added.
3. Look at the calendar dropdown again, the timezone has duplicated! Adding back the home timezone in "Choose Locations" allows you to change it back but now there's three options in the dropdown, since one is still duplicated. I will attach a screenshot.
