Ron, I think we may be thinking of the same switches but in different names.
First, the crank should never be able to reverse at all. It is locked to the carousel via a pin and notch under the carousel.
The two switches at the rear are called Transfer & Mute-Play. If someone has Gepettoed with the adjustments as often happens as switches get pitted and erratic it can cause the actuator rollers for either switch to ride the cam and flip the switches. The cam rollers that operate the switches are help slightly off the cam by the keepers. If those are tinkered with so that the rollers ride the cam and the switch actuator screws are set too far the switches than be actuated by the screws on the cam ramp instead of the ramp itself.
The first 1800 I bought had all of these adjustments wrong..
I think you have a combination of tampering and sluggish operation.
Here are scans of the setup for those two switches.

The Reversing Switches are at the side of the junction box and actuated by the plunger that is released by the crank. that is another trouble spot if it has gotten sluggish due to old oil. With power off just pull the crank back as if it hit a pin. the plunger should drop immediately.
Here is the functional for a 2204:
