Computer not detecting any SSD in M2.1 slot

I just had to do a clean install of Windows onto my PC and afterwards I noticed that the M2.1 slot is not detecting my 1TB PCIE NVME SSD. The M2.2 slot is working just fine and is picking up my other SSD. I've tried reseating it and updating BIOS and so far nothing. Anytime I check disk management I only see my second SSD and in BIOS the M2.1 slot keeps saying not detected. I have no idea if I'm just being special and missing something very obvious but I would appreciate any help. My specs are also listed below:
