You need to read up on how relations work. Checkout: [http://wiki.openstreetmap.org/wiki/Relation][1] With your specific case, each of the segments along the shoreline are polygons that are members of the a multipolygon relation. In Using Potlatch2, if you click on one of the shoreline segments then click 'Advanced' at the bottom-left you'll bottom-left. You'll see the relation box containing 'multipolygon lake'. Double click on that and you'll get a popup window which allows you to view and edit the relation itself. relation. Regarding the missing name of the lake, my guess is that the relation is broken somehow which is stopping it from rendering on the main map. This could be because the segments don't form a closed circuit. Unfortunately that's the limit of Potlatch2. You will have to start playing with the more advanced JOSM tool to fix that one.
