B20D Odometer Issues

Hi, I've got a B20D that's logging different engine hours on the display as opposed to what's being broadcast on the CAN bus.

 

This is the CAN bus data log in terms of the engine hours (my apologies for the formatting):

Using the FMS spec, I can see that these messages seem in the correct format and increment once every 3 minutes (as expected from the spec). This value corresponds to 19051 hrs.

 

However, on the dashboard, the value on the display reads 32626 hrs. I see no correlation between these values and I can't figure out where this value comes from, either.

 

My question is this: is this issue common on these vehicles?  Or is the display reading in different units (the ratio between the two is about 1.71)? How would I go about using these values for client feedback on engine hours?
