Kirk,
Thanks for the reply. In pulling together the test files I discovered my issue. I had the tag column twice in my export and had edited the instance in another column instead of column 243, which is what I was using in Stationary Pad. Once I set Stationary Pad to the same column I edited (from 1 to 0), it worked as expected.
And yes, I do have 200+ columns. I built a workflow for one person to export all metadata and another person to import all metadata and declare which fields they want to import with Stationary Pad. I'm sure I'm missing some fields, but here's my export text template:
