Hello everyone!

I have purchased two M2 SSD (LEVEN JM600M2-2280 1TB) to setup RAID1 on my AB350 Pro4 motherboard. But the SSD is not working in the Ultra M2 slot (M2_1).
SSD is fully operational itself. I have tested it in the M2_2 slot.
PCIE4 and SATA3_3 slots are empty.

Here are photos of the SSD package:

The photos of the SDD itself:

MB BIOS version P3.20.

Q1. How can I solve this issue where an SSD is not being detected in the Ultra M2 slot?
Q2. Is it possible to create a RAID1 between M2_1 and M2_2 slots at my motherboard??
