MISSING ALL THE APPLIED LOAD (TO PLATES) WHEN RENUMBER PLATE

Hi All,

I got the problem with my model, for a reason I had to renumber all the plates in my model, but after that, all the loads which had been applied on these plates are missing. In the orther hand, when I renumber beams or nodes, the applied loads were kept perfectly. Can any one tell me how to go around with this matter?

Thank you.
