Anachronism drop at the start of FOM

I have been playing CoV for sometime and have been trying to achieve certain stats. By the end of the first game I have around 81 adaptation but it drops to 66 when I start FOM. I’m not sure why it is dropping but I want to avoid the drop. Could anyone help me figure out what I am doing wrong?

Do you do anything old fashioned?

Not really, I usually keep my character quite modern (choosing change when possible). However my character is a priest but I’m not sure if it has anything to do with that.

This will help.
