New extended field OVS cannot display ID and trace

Hello Experts,

I add OVS type fields in supplier invoices, using the system standard project task OVS.But I can't give you a description.

Reference standards, there will be a description to bring out.

Please kindly check why the description of the field I created cannot be brought out. Is there a problem? Is there something that needs to be configured?

Thanks & Regards,

Grove
