Rendering/freezing track is off time.

Did some pitch correction with nectar on a track, and when I render it it's phasing with the original track. Any reason why this is?

In addition to this, I tried to just render the track outside the project to see if that made a difference and it would make a very weird distorting sound at the correction parts. This was only when I exported the track.

Any help is appreciated.
