Egg on face -
I had been trying to fix up some tables so they displayed in Kindle Previewer and I created a separate InDesign file for mobi in addition to the one I used for the ePub. (This one had the tables reformatted as text) Well, I was viewing the output from the "Export for Kindle" plug-in in inDesign. Not the Calibre converted version.
So I'll just back out the door here and thank you for your help and sorry for wasting your time.
