Broken CFP Selection

I am in a 14 man online dynasty. 7 of us are in the MWC conference and the other 7 in MAC. We all chose small schools and we just finished the conference championship in year 3. I have no explanation for how Temple did not make the CFP. They went 12-1, won the conference, and their only loss was to #13 in overtime by 1 point. After conference championship, they were ranked #12 in the country. For some reason the 12th spot went to # 20 southern Miss who won the sun belt.  9-4 Texas also made it. This selection does not follow any rules or logic of CFP selection. Any thoughts on what happened?
