Description:
I create a new 2 columns section. Move some text there and save the file. When I re open the file the second section has merged with the new 2Cols one and all the text is toghetern in the 2 sections col

Steps to Reproduce:
1.Open the file "Prueba 2 columnas"
2.In pag 2 there is a sign "insert a section here"
3.Insert there a new section. Format it as two columns
4.Cut the text below this new section until the page titled "El Calafate" and paste it in the 2Col section
5 Remove any new line to adjust the presentation
6 Now you have some text in two columns. After it a section change with the title "El Calafate" and the table
7 Save it and close it
8. Reopen the file. 
9 Now you have lost the section of "El Calafate" and all the data was moved to the 2 Col sections ( File Prueba 2 columnas final.dos)

Actual Results:
One section is lost and the text is merged with the new one

repro 7.3+.
Used bibisect-linux-43all to confirm the same is true already in LO 3.5, so likely inherited from OOo.
Used Word 2003 to confirm this is a FILESAVE issue - since Word also imports the last page in column mode.

None of this is really surprising, since LO and Word handle sections completely differently.

Saving as DOCX format emphasizes the difference (probably because DOCX handles continuous sections differently from DOC to allow flexibility in desired results).

There are several ways to do this differently that I noticed. One is to not insert a section, but just simply insert the desired columns directly.

The other way is to change the regular page break to a "section page break" by also setting the page style to "Default Page Style".

I suppose there could be some logic on export to emulate this a bit better, but this is a very tricky area. Setting to NEW since all the similar bug reports I can remember are related to import instead of export.

This is an easy minimal reproducer: simply open and save as DOC/DOCX.
