Did a little more digging. It may be a course issue rather than a user issue.
1. logged in as an instructor with over 25 courses, and it only offered me three courses to import from.
2. Tried another instructor who has 12 courses and only two courses are shown to import from.
3, Tried another instructor 12 courses, 10 show up.
I cannot find a pattern.
Aaaaarrrgghh!
