Hi TI
Why is the 27pin inconsistent with the manual?

Hi Rain Wang,
I'm not sure why you are seeing an error, but in my PCB editor both packaged versions of the ADS131M08 pin 27 is labeled correctly as NC - see below.
Can you manually change this pin in your PCB editor to be NC? I know this option is available in Altium.
Or, you can just connect this pin to AGND or leave it floating, as per the datasheet
