bug report dsPIC33EP64GS805 ADC1 pins incorrect in Pin Manager Grid View

MPLAB X IDE v5.25
Code Configurator 3.85.1
OS: Windows 10
dsPIC33EP64GS805 
ADC1 peripheral
 
Short version:
The pins laid out in the Grid View of the Pin Manager for the dsPIC33EP64GS805 don't match the datasheet (page 6). The names laid out in the ADC1 Selected Channels dropdown also don't match the datasheet (page 6).
 
More descriptive version:
The datasheet (DS70005258C - page 6) pin diagram has analog inputs tied to pins 1, 4, 22-30, 34-37, 39, 47, & 48, with “an1alt” and “an2alt” on pin 2 and 3. The names of the pins vary from AN0 to AN21.
 
MCC claims analog on pins 2,3, 22-30, 34-37, and 39 (as well as an input on 38). The pins are named in order from AN0-AN14, minus AN12 and 13. MCC confusingly adds ADC0 and ADC1, but custom-names AN0 and AN1 in the peripheral to match, while leaving them assigned to different pins in the pin manager.
This, by count, is only 15 analog pins, where the datasheet claims 17.
 
I'm trusting the datasheet, but want to make sure the bug is reported and also that anyone else using MCC for this part is aware.

    Does this IC come in different packages with different pin outs?

    The two missing inputs (RB5/AN19 and RB6/AN20) are shared with JTAG pins.
    Do you have JTAG enabled?

    Nope, the TQFP48 is the only package in the datasheet for this particular configuration (64GS805), and the only one in MCC. Other configurations of this family have multiple packages, but not this one.
     
     
    And I do not have JTAG enabled.
     
    Part of the bug is the missing analog pins, and the other part of the bug is mis-mapped analog pins.
    I can't tell if Microchip copied the code for the analog from a different part/configuration and didn't change it and no one has caught it yet, or if there's something wrong with my particular installation. I'm skeptical of both, but clearly something's not quite right.
     
    Also, Happy New Year!
