Hi Chris
that sounds like a bug we briefly had in our dev version that was fixed months and months ago. You should grab a new one (or Nick or Zeke can post an update if that is the newest one we have posted)

I'm not sure whether this is an unstable version or not but when I use it the subsequent inversion step does not work:
I'm happy to send the m3z file if you wish to debug it.
