invisible fields

How do I delete invisible fields that are in all the pages of my draw files? When I print or open print preview they are visible in the top left corner. Yes, I know to click on a field to edit it, but as I said it is invisible! –driving me crazy

Can you please upload a reduced and anonymous file here?

To upload, edit your initial question and use the paper clip icon. Thank you.

It might also help to know which operating system and which LibreOffice version you are using.

Are they in a layer that is set not to be visible but to be printable? Along the bottom there are three default tabs on my installation: Layout, Controls, Dimension Lines. If I right-click on each and select Modify Layer, I get a dialog box with, amongst other things, tick boxes for Visible, Printable, Locked. Does one your layers have Visible unticked but printable ticked?
