Comments from Submitter:
The inventory in the instruction book shows only two of trans green and trans red for plate round 1x1 items. Also the instructions never use more that two for either A or B-models.
I'm guessing the third one is an extra part since it's in bricklink inventory but i cannot confirm that.
