We work on a monthly report which use sheet to separate each month report. On each sheet we would have around 3 - 5 A4 page length. When exporting to PDF, it will generate all sheet in one PDF instead of just the sheet selected ( active ). While we can split the PDF later by using other software, it's combine all the footer page numbering. Example : Sheet 1 call "Jan 2016" have four page Sheet 2 call "Feb 2016" have three page Now the footer will shown as page 1 of 7, instead of page 1 of 4 It should take account of "Print only selected sheet" options
Maybe you are using the "Export as pdf" icon, going through Menu/Files/Export as pdf - [General] - Range - Selection, it does how you want. Resolved as not a bug, please if you are not agree, reopen it. (Enable Menu/Tools/Options/LibreOffice/General - Extended tips, and on the icon the tip shows "Export the current document directly as PDF, no settings dialog is show")
