No text in deja dup window

I noticed that Deja Dup's "Back Up" window doesn't have any text labels in it other than the large "Backing Up..." label and the text in the Cancel + Resume Later buttons. I expected to see labels describing what is happening (incremental backup vs full backup, for example). If I open the twisty, there is no text in the details area (though the scroll bars act as if there is text in the window).

See the two attached screenshots, one with the twisty open and one without.

To reproduce:
1) Make sure Deja Dup is configured
2) Plug in/turn on your backup drive (mine is an external driver, I haven't tried a cloud backup w/ DD)
3) Bring the Deja Dup window to the foreground
