It's a bit odd as 21D4/21D5 is the Z16 G1
Z13 G1 should be 21D2/21D3
(https://psref.lenovo.com/WDProduct/ThinkPad/ThinkPad_Z13_Gen_1)

They're both based on the same design and system FW so I'd expect the issue to hit both platforms.

I plan on testing this on my system but haven't done yet. I can check the Z16.
