Problems with rules and Gmail folder

I see that there other people who have had “rule problems” in the FAQs so I will read those posts first!

Secondly, the folder structure on the left shows a “Gmail” folder in italics, and I’m not sure where it’s coming from just at the moment. Some even appeared in the “Trash” folder, labelled GMail1, GMail2 etc.

Is it something to do with the fact that I have imported mail and contacts from Outlook?

PS I am using the Free version for now, it was recommended in a computer magazine recently.
