Can't see mob levels in main window

Got a strange issue on my wife's computer, on her main window when you are walking around mob info doesn't show above the mobs. The only way to find out what level anything is, is to actually click the mob and look at the targeting bar.

Go into options and makes sure floating names didn't get turned off. I believe there is a hot key for it too, which she probably hit accidentally.
