ADCu7060 using external reference

We are using this device with an external reference of vref- = 0V and vref+ = 2.5V

 

If I set the HIGHEXTREF bit of adc1con I am only getting half my range.

 

If I do not set this bit I am able to use the full range.  However I am not getting the readings I expect.

 

What is the proper configuration for this register using these voltages

 

These are my other settings for adc1con

adc1conDefaults = BIT15 + BIT11 + BIT4
