Did the text show in the demo game? Are you using the windows or mac version of the editor? If mac, then are you using TTF fonts? Have you enabled shadows &/or borders for the TTF fonts? if so, then on mac the text will not display as borders & shadows seem to prevent the text from displaying. On windows activating borders breaks the space between words instead.
I'm sure the devs will have it sorted out ASAP. Hopefully for the next update.
