All office sheets at opening are not ready to type

When I open, say Writer, and start to type I get how ever many new sheets for each keystroke until I look up and realize I am not getting typed text but several new sheets. I do not understand purpose of this and would prefer to open a sheet and type and have it appear in the document, spreadsheet, etc.

Please can you detail your OS and your LibreOffice version?. Can you also detail step by step what do you do when you have the issue?
