Hmmm sounds like a glitch in your save file maybe. A similar thing happened to a player with Tali'Zorah in Mass Effect 2 that allowed him to have her as the only survivor of the suicide mission. Basically, she'd survived it along with Zaeed, but it also listed her as dead at the same time. So, he then was able to kill Zaeed during his loyalty mission, leaving him with Tali'Zorah as his only survivor.
Sounds like you might have a similar problem in that Kelly is both alive and dead in at the same time in your save file, and the default assumption is she's dead.
I would recommend either checking your save file from ME2 if you know how, or else if you don't (I don't) then maybe someone else who knows how to read and edit save files can help you.
As for fixing it in your current game, pretty sure that's not possible, you'd have to fix your save file (if that is indeed the problem) then start a new game with the repaired file.
