THS3061: Why THS3061 and THS3062's CMRR are so different

Part Number: THS3061
Other Parts Discussed in Thread: THS3062,

Dear teams,

THS3061 is a single amplifier, and THS3062 is a dual amplifier. Their electrical characteristics are almost the same. But their CMRR plot are dramatically different, Fig 31 on Page 11.

Can you help explain why their CMRR is different? Is there any mistake here?
