Compile page break cannot be deleted in MS Word

Hi, I set the compile to make page breaks between chapters. I’m working from Scrivener 2 to MS Word 2013. When I try to add a heading at the start of the chapter, it creates another page. I cannot select the page break symbol to delete it. I have only ever had this problem with Scrivener compiles, never with documents prepared in Word.

Is it the way I set the compiler? Is it a bug? Is it my old version of Word being incompatible with Scrivener 2?
