MAX30210 I2C address mismatch

Question

Hi, 
 We are using MAX30210 Temperature sensor in our design. We have connected A0, A1 to ground, Hence, the I2C Target address should be 0x80 as per datasheet. However, We are observing that the target is not responding to 0x80. But its responding to address 0x40 and 0xC0. I have attached schematics for reference. 
 
 Thanks
