My bottom tray is not the same as my top. My bottom tray covers half of my wisdom tooth. Is this at all normal? (Photos)

My top one is fine and doesn't include my wisdom teeth. However my bottom tray, one side is longer than the other. My left side of the tray doesn't cover my wisdom tooth either, but my right side covers half of my right bottom wisdom tooth. I am now experiencing pain in that wisdom tooth, and dentist says I might need it get it removed even though she had originally said Invisalign would not have an impact on the need to extract my wisdom teeth because Invisalign does not work with wisdom teeth.
