Did the same process to the next two machines, but they kept vending two bottles at a time. I watched from underneath as I test vended. The second bottle just rolls over the notch that sticks out from the shim and drops. The notches on the other shims catch all the cans and the one Gatorade selection that does work, preventing them from falling down into the chute.
I imagine you may need more details, but any suggestions up to this point.
Thank you for all that reply.
