Envelope Transform>Warp not functioning correctly-multiple errors

In the attached video, I select the object I want to warp.

I select the Envelope Distort > Warp option from the Edit menu.

If I adjust the slider to 0 for percentage, the preview should show no distortion but it does.
This is true if I enter 0 manually, or drag the sliders to 0. 
If I change the distortion to Vertical, only the distortion map changes, not the preview of the distortion. 

If I change the Warp Type, the distortion map barely changes and the sliders don’t work as expected

If I radically change my settings, then change Warp Type, nothing changes in the preview or the distortion map.
If I toggle the Preview button, nothing happens. The incorrectly distorted preview persists.
If I Cancel, the selected object should remain untouched. Instead the incorrect distortion map is applied
