The top of my Invisalign tray doesn't sit flush against one tooth - is this a problem? (Photo)

I started Invisalign 3 weeks ago; I am on my second tray. Starting with the first stay, I noticed that the top of the Invisalign tray bulges away from one of my lateral incisors. This remains the case in my second tray - is this a problem? The attachment on that tooth fits in the tray, and the tray fits well on the surrounding canine and central incisor. I would hate to get off on the wrong foot. Two photos of so-so quality attached.
