Green Text is Missing in Upfront

I'm working on getting a new site setup, so I figured I'd try out Upfront. It was working great for awhile, but after making some changes, I noticed a whole bunch of the text is gone.
On the menu to the left, I can see the line for "Profile" and I can click it, but there's no text. Also for "Post/Pages", I can also see the line, but also no text. None of the "draggable elements" have descriptive text at the bottom of their icon. On the page itself, I have dropped in a Post section. The title of the post and the "read more" text are missing until I hover my mouse and then the text appears.

Any idea what may be causing this?
