Columns

I have hundreds of pages with each page divided into two columns. I have been doing this for at least two years with LibreOffice. Never had it been a problem.

After the second last update, I find that when I open up a page I had saved, no columns. I have to reset them. I am now using ver 4.4.1.2. I still have to reset the columns.

Obviously, something was changed in the updates.

What is wrong here?

Thanks for any help.
