Re-publish changes Page Pane settings

Recently many of my published reports changes from showing the tabs at the bottom to the page pane on the left.  I found the setting in the report viewer that allows me to change it back to the tabs but every time I re-publish the report with updates it resets that setting and I have to go in and change it.  Is there something I can do to retain that?  a setting in the desktop app maybe where I am building the report that is flagging this?
