"Continuous section breaks" automatically turning into "next page section breaks"

I have a document that has several sections, which I formatted in a continuous manner, meaning that I do not want any "next page section breaks". Some of the sections are formatted in two columns and some have one column.
I inserted "continuous section breaks" wherever necessary, and many of these continuous section breaks are automatically turning into "next page section breaks". Even if I delete the "next page section break", the previous "continuous section break" which luckily hadn't turned into a "next page section break" will automatically become one, after deleting the one after it. Something mysterious is occuring in this document. Can someone please assist me in setting up the breaks properly?
