"lightbox" Text in TosRus Galleries

I’m having an issue where I’m seeing the word “lightbox” in the ToRus version of the gallery. This is the only effect that is showing this. I’m using NextGen Gallery with your plugin. Any ideas? I’d really like to use this effect, but the lightbox text is unacceptable. See it here: https://50.87.248.173/~boydtono/local/gallery/

Thanks in advance! ~Mike
