Question What did i do wrong? Cloning windows

[BillWiTheScienceFi]

I was trying to clone windows onto my new pcie m.2 SSD and i went through the instructions and used macrium reflect, once it was all done copying its now telling me I have 2 of the same storages but [A:] should be the 2TB new ssd, so why is it saying 465gb[C: is my current one w/windows]? Did i do something wrong?

Going into disk management its showing the rest of the drive as unallocated, I alocated it before all this now if i try it, it wants a whole seperate drive letter from what i just copied windows to...
