Keyboard layout menu bug

I’m running WP 2.6.3 on OS X 10.11. My computer’s keyboard layout is set to Colemak.

When selecting a keyboard layout in Input, all works fine. However, when the window is relaunched, the layout selection box displays the name of the item following the actually selected item. Data collection and the keyboard heatmap are unaffected by this bug; it’s just the dropdown menu.
