Problem with text wobble

Hi there,

I'm trying to animate some text going around in a circle, but the text, no matter the font i choose, wobbles.

See this video, and pay attention to the text, to see what i mean:


This effect is also seen in export:


Also there is a bug in export that makes a ghost in the very first frame, not visible in Motion, only on export.


I've also attached the motion file.
