MID Emulation

[speralta]

Hello,
I'm not sure if I have something set incorrectly.  But the MID emulation on the Control panel doesn't seem to work properly.
For example, if I select "DIST" and then select SET and try to input a value, the buttons do not map to any numerical values.  It also doesn't show any number except for "78 90".  Pressing any of the soft buttons that should be numbers only selects previously mapped values like "Timer1, Timer2" etc.  I have to press either the "BC" or "Clock" for it to display the proper text on the screen again.

Is there a setup issue I have?
The head unit is an Eonon GA9449.
Thank you!
