1. go to any course and choose Import.
2. Select any other course to import from.
Look at the numbered 'stage bar' that indicates which import stage you're on:
1. Course selection / 2. Initial settings / 3. Schema settings / 4. Confirmation and review / 5. Perform import / 6. Complete
As a minor point, this bar didn't appear on the first page where you select a course, which might possibly be considered a bug. However, more obviously, when you are on the second page 'Initial settings', it actually highlights both the first and second stage as bold (current) even though you are clearly on the second page not the first.
I don't intend to fix this (sorry) but it was raised while testing something else I'd done so I'm filing the issue to have it on record.
Possible solutions include leaving out the current step 1 and changing the numbering (so step 2 becomes step 1), or fixing it so that only step 2 is highlighted.
