SRB Details do not stay together on a page

OO 3.2 and SRB latest version

I found that when placing  multiple fields in the"Details' sector of a 
report the "Keep Together" do not works properly

When the 3 fields who are placed on top of each other the must always 
stay together on the same page ,  now they can   split up  over two 
different pages depending on the place there rest at the botom of every 
page .

Do i mis understand this "Keep Together"  function  or sould i fill a 
issue about It ? or is it already fixed in a future release :-)
