When creating or adding cards to the deck of cards for a Confluence page of tabs, there is a line or row space/return automatically applied.  Or maybe it is an automatic paragraph spacing.  Anyway, this causes the heading of the card (tab) to display with one or many line returns between the tab and the title of the tab.  The only way I have been able to ensure this doesn't happen is to go between each card in the deck of cards and backspace or remove any spacing between cards.  Sometimes this has to be done multiple times (enter line/space, backspace or delete line/space) before it "takes" when in the Edit mode.  This "issue" is not known to all general users/editors of Confluence and generally is not noticeable until the page is Published/updated (unless the user is viewing in Preview during Edit mode).  It is very annoying to have that as a default in the Macros - Cards template feature.  Perhaps the default can be removed or updated so that it does automatically apply that format within the card macro?  Of if there is another way to to update the Cards macro or usea a completely different macro to use for tabbed pages within a page?
