The declaration system is closed or invalid: if the property declaration system is closed or invalid, it may not be modified. Usually, the professional title declaration system will be closed some time before the evaluation results are published, so as to avoid frequent revision and submission of data by the applicant. If you encounter this situation, you can contact the professional title evaluation institution or the relevant department responsible for the declaration of professional titles and ask if you can open or repair the system.
Limited modification authority: Sometimes, the title evaluation agency will limit the applicant's modification authority. For example, some institutions may only allow the applicant to make one modification before the evaluation results are published, while others may not allow the applicant to make any modification. If you encounter this situation, you can check the notice or announcement of the professional title evaluation institution to understand the specific revision policies and requirements.
