New Crucial 4TB SSD Only showing 2TB

[solaris54]

Crucial 4TB SSD already switched to GPT only showing 2TB when I go to To Disk Management to scan the drive. I have done a lot of searches and so far nothing works. I already have a 8TB conventional hard drive installed so I don't think it would be the motherboard
or drivers that need update. I am using a hard drive docking station to test the drive so not sure that is the problem. I wanted to check the drive before installing in the computer.
I just want to find out before I end up sending it back.
Any suggestions would be appreciated.

what does it show in BIOS? is it 4TB there?

It shows the correct Crucial model number of 4TB and also the same in the Device manager. Maybe it is the USB reader that I am using or it needs to be installed on the MB. It seems like I have had this problem before but I
can't remember how I fixed it.
