Is this a glitch again?

The one with the bottom and top on her wings is fanart.

Her outfit is different in the actual show than the fan-art that was released for the girls' Enchantix transformations. So, you could base her Enchantix off of either of the images but the more commonly used transformation is the one where her outfit is mainly purple. (The one with only one set of wings)

Neither are fan-art. They're both official. It's just one was featured in the show, while one was just released as official fan-art.
