Hmm....I own a V63 & VF56 & never has trouble with the new style bottles, only in machines with vertical columns stacks like a V44, V80, etc.
Raise the floor of the bottle port(s) there are holes & rods that will either raise or lower the "floor" of the vending port(s) in relation to the gate/roller for that selection/shelf the larger the bottles diameter, the lower the "floor" needs to be (and visa versa)
some of the ports however have a threaded rod & a lock-nut holding them in place because these are the "keystone" positions that hold the rack together, they can be adjusted also, but only do one at a time or your rack may fall apart...
there's usually an instruction label on the inside of the door to show how to adjust the shelves & ports for varius sized bottles.
