LTM4620 POWER GOOD abnormal behavior!

Hello I am so glad that now also linear is part of Analog Devices and I can ask my question in this good community.

In our custom board we used LTM4620A for 3.8V and 2.3V output. both output voltages are good without any problem. Power Good of channel 1(3.8V) output is 5V but Power Good of channel 2 (2.3V) output is 0.8V could you let me what is the problem?

Attached is the schematic.

any help would be greatly appreciated.

Best regards
