Date Format Problem

When displaying long date ranges, the string "YYYY" is displayed instead of the year. It also appears in tooltips when hovering. Screenshot below.

While poking around I also found this additional date format problem when zooming in. Looks like Months show up twice and the year string shows up a second time, but as "YYYY".
