You can't set 'Options' for field Inspection Type

Hello, we use ERPNext v13.27.0 (HEAD). We have different types of inspection types for our Quality Inspection. Since Inspection Type is a ‘Select’ field, we were able to add ‘Options’ for that field until now. However, after the update, we are unable to add/remove options for the Inspection Type field.

It is a bug that has come after the update. Can someone from the ERPNext team please fix it @JayRam @rmehta ? Thanks!
