documents saved with double column revert to single column when re-opened

[danw]

I am a pastor and I type out all of my messages on landscape and double column so that my notes are on half sheets. Since this morning, when I open up any of my old sermons that were saved as double column, they are all landscape single column, though in the layout menu, double column is still highlighted. I have to select single column and then double column in order to get it to change back to double column. However, when I save it and close it, it all reverts back to single column when I re-open it. Can someone please help me with this issue? I have tried shutting down my computer and re-starting it, but it continues to do this.
