My one thought (and this is grasping at straws) is that perhaps the flight was going to divert to MCI for whatever reason (fuel, weather, mechanical, medical) but the situation changed and they made the decision to continue to CLE after flifo had been updated to show the MCI stop...

I have never seen that status message before though for CO/UA, though.
