I want no messages recovering document.

I try to close a session libreoffice impress bij closing my Raspbeery pi 3 without clossing correctly the running document.
With VNC server i cusseeded starting an document but i donot know how to close it corretly.
So i shutdown my Pi, only bij starting again een new document i became an message i cannot handel remote.
Only i use Remote with bluetooht that wordk perfekt but for my it’s better doning it with een wifi connection en vncserver. Then i have one tool in us. Can you give me an solution foor my Pi to get no more messages from cecovering my not corret ended document.
