Page break shows automatically when i click "save" an excel file

(1) Page break shows automatically when i click "save" an excel file. So (2) I go to "Options - Advanced - Display Options for this worksheet" to (3) unclick "Show page breaks" and then it's ok. But when I open or create another excel file, i need to  repeat step (1)(2)(3) again. How to turn off this automatic page breaks in excel?
