I am writing documents with Libreoffice. For some reason, recently I started getting a format that showed two consecutive pages side by side, and I have been unable to change this to showing just one page at a time.
At the bottom of the window far right is the size slider. Next left to this are 3 icons. From the right 2 pages joined together - 2 pages separated - single page. One of these will be bold. For a single page display click on the left icon.
