Infopath and Site columns

When publishing a form in infopath, you are given the ability to match fields in your form to site columns.
Be careful not to create two site columns with the same name in the same category. Infopath has a bug in that it will let you see that you have two columns with the same name, but will only let you pick the first one. It seems that it matches by name, and not by the internal name. You can pick the second field, but if you go back to edit it again, you'll see that it goes back to the first field.

This is only an issue when publishing to a sharepoint site.
