One of my teeth doesn't fit my tray, what should I do? (photo)

Hi, I'm an invisalign user who got two upper 2nd premolars (left&right) taken out before starting invisalign. I'm currently @Tray #22 when I realized that my upper 1st molar seems crooked and did not fit into the tray. I tried on past trays up to #18 (which is all I have brought me to school) but the molar seems to be crooked and not fit in any of them! What shall I do??
