Bridge MAX96724 and MAX96717 via MAX96717/96716

I am using a pair of MAX96717 (ser2)/MAX96716A (des2) to bridge MAX96724 (des1)/MAX96717 (ser1); the link is: max96724=0x4e -> max96717= 0x70 -> MAX96716A=0x60 -> MAX96717=0x84; Link A, PHY mode 2x4,

I am attempting to pre-configure SER1 from 0x84 to 0x88, then add I2C translation on SER2: 0x44 = 0x84, 0x45 = 0x88. However, after adding the translation, max96724 switches to the wrong link, then re-modifies 0x88 to 0x8c, causing subsequent configuration of 0x88 to fail. Why does DES behave this way? Is it related to the configuration order of DIS_REM_CC and DIS_LOCAL_CC?

Thank you very much.

This is the I2C log of max96724 directly connected to max96717.
