Overlapping items in Swimlane export
Problem
Some users have reported an issue with overlapping items in their swimlane export. This can happen when items are moved within the swimlane while the publishing is being processed.
Solution
Here are some things that have worked to resolve this:
Move an item anywhere and then back to its original place, and re-publish
Invert the headers and re-publish
Duplicate the view and re-publish
