Ver 13 settings not matching Docs after update from Ver 12

Did successful upgrade from Ver 12 to 13 and now at:
ERPNext: v13.36.1 (version-13)

Frappe Framework: v13.36.2 (version-13)

According to docs for ver 13
https://docs.erpnext.com/docs/v13/user/manual/en/accounts/articles/discount_accounting

are supposed to have check boxxes for discount accounting in selling and buying settings pages. They are not there. Did something go wrong in upgrade??
