I have version 18.104.22.168. In Calc, default lines mysteriously appear that render printing a spreadsheet impractical. Repeated use of the LO help procedure FAIL. If you can provide a precise step by step process to overcome this bug; it will be greatly appreciated.
Failing that, can I revert to an older version? Perhaps the version presently touted as an upgrade doesn’t have the issue quite new to my LibreOffice.
