Failed to update setting: invalid cost currency '{value}'. E

Error message

Failed to update setting: invalid cost currency '{value}'. Expected: usd, cny, rmb, yuan.

What it means

Settings update validation for the cost currency key: the value is not one of usd, cny, rmb, yuan (rmb/yuan are aliases of cny). Rejected at set time so cost formatting never receives an unknown currency code.
