I have a custom Discussion Board list definition developed in SP 2010 which is upgraded to SP2013.
The issue is the ratings column shows numbers even if the stars option is selected in the Ratings Settings. I have also disabled and enabled the Ratings settings without any success.
Any sort of guidance to resolve this issue would be of great help. Find the field from schema.xml below. Let me know if any changes are required.
