You'd better contact the editor or editor-in-chief, explain your situation, and tell him exactly what you found and see how to solve it. Be sure to save your manuscript as much as possible (Luckyman20 12). This is because there are revision records when editing word documents. The solution is to select, save and unsave revision records in the Word menu. Then save a new file and submit it.

In addition, when you submit a paper, you approve the paper without carefully checking the pdf document. Be sure to pay attention next time.
