linea in diagrame

Hi, How can I remove some lines in the diagram that resemble page divisions, when I print they don't appear, but they bother to work, I don't know what to activate
thank you

Hi,

Page boundaries lines can be activated / deactivated via the "page boundaries" entry in the diagram drop down "..." menu in the top diagram editor toolbar
