When an evaluation structure (evaluation groups, evaluation codes) is configured, it doesn't carry over between seasons. However, you can copy evaluations from previous seasons.

In order to copy evaluations from one season to another, navigate to the player evaluation setup page (Setup->Statistics/Evaluations->Player Evaluations). Then change to the season you want to copy from using the season dropdown. Then click “Copy” under the list of evaluation groups, and copy them to the current season.
