Gate Information - Repositioning?

Today, N803NW shows on Flightaware as arriving ATL into Gate F7 from Sao Paulo, then departing as DL176 from Gate E26. That was an hour or so ago. Now, Flightaware is showing DL176 departing from Gate E17. Same aircraft.

What’s going on? Is the aircraft repositioned (possibly twice) or is FA getting incorrect gate info?

The plane can be moved from its arrival gate to its departure gate and at times, gates change.
