How do I install the CSC file through Odin?

I installed the XAC firmware on top of my BMC firmware in order to give me the standard Samsung stuff instead of my carrier stuff.

Now when I check CSC info in the Phone Info app it's all blank. The only thing that shows is Product Code and Mobile Operator. Everything else is blank.

I have a CSC file but the option in Odin is greyed out.
