Question M.2 shows up twice in bios

[Rlafle565]

Recently got an m.2 for my birthday and decided to put my windows on it. After getting it set up and installing the fresh copy of windows I restarted my computer and found two copies of the same m.2 one being the boot manager that restarted my computer but wouldn't boot to windows and the other being just the drive itself.
