TESU no longer accepting SDC Cybersecurity

[P226mem]

I was looking at the transfer link. I noticed on SDC transfer list that the sdc 331 courses transfers as CYB 421 at TESU, but that he already has CYB 421 (1 credit version from teex transfer). I don't know if that is what tesu was trying to say in the email about the specific course not being accepted, or something with that can be part of the appeal. remove the teex 1 credit if the 3 credit sdc can happen? Or maybe they changed their minds altogether and that's a bad idea to ask.
