 **Why this happens**: Adding codes programmatically (e.g., Python dict.append) without checking for existing entries. Always verify the codes array has unique `field` values before saving.
-1. **Dictionary codes** (table=`appcodes_kv`): Use `parentid=` cond, `valuefield: "k"`, `textfield: "v"`. Data comes from `init/data.json` Format B.
-2. **Foreign key codes** (table=other table): Use `valuefield: "id"`, `textfield: "display_field"`, no cond needed. References another module's table for dropdown population.
