Argon one v2 not fully powering off

Hi, I have brought 2 argon one v2 cases with m.2 expansion

Both have the pins set at default

One of the cases has a 1tb ssd m.2 wd blue and the other has a 2tb ssd m.2 wd blue

both are using retropie with same firmware etc

Both are using Raspberry pi4b 2gb boards

The one with the 2tb ssd does not always shutdown fully it keeps the red power light on but you can’t access it via ssh so it appears to have shutdown.

the other raspberry pi with the 1tb works as it should.

No hubs or anything extra plugged in and both use official argon psu

Both just using bluetooth ps4 controllers and 1 wired keyboard

Any suggestions?
