An unfortunate side-effect of deleting ‘Continuous’ Section breaks in Word is that they tend to cause the preceding ‘Next Page’ Section break to be converted to a ‘Continuous’ Section break. A workaround is to convert the Section break to the same kind as the one that precedes it, then delete break. You can do that via Layout>Page Setup>Layout>Section Start.
The following macro automates the process. Simply select a range spanning the unwanted break before running the macro.
Code:
Sub DelSctnBrk()
Application.ScreenUpdating = False
With Selection.Sections
.Last.PageSetup.SectionStart = .First.PageSetup.SectionStart
.Last.Range.Characters.First.Previous.Delete
End With
Application.ScreenUpdating = True
End Sub
