'All Mail' Folder disappeared after Mavericks upgrade

Before upgrading to Mavericks my mail app had an 'All Mail' folder in the G Mail section on the left hand side of my mail app. This area below 'On My Mac' has folders I created and below that a section that automatically appeared called G Mail. In it is obviously all my g mail but one folder that was particularly useful in finding all g mails that have been sent, deleted, etc. from my Mac, iPad or iPhone is gone. Does anyone know how to fix this?
