You're right, when the mobile theme loads, vBadvanced CMPS is supposed to be disabled, and it isn't.
For example, here is the mobile style on the problem site:

Mobile theme on a non-problem site:

That gives me something to work at. Have to backtrack how I managed to disable vBadvanced for mobile in the past...
