TruenNas Scale is only showing half the RAM i have installed

I’ve found where others have had this issue, but all of them had multiple GPUs and their BIOs was allocating system RAM as video RAM for the one of the GPUs. I only have one discrete GPU installed, no integrated. My Bios see the RAM and if I install another disk and boot to windows it sees all 32Gb of RAM. Can some help me figure out the next step in trouble shooting this?
