By "latest", do you mean the one on Dec 7? That is the only one up for review, though there have been numerous edits since then.
If so, just what are you trying to approve? When I look at it, it won't show me where it it was located and where someone wants to move it to; so it's not something that you can confirm is correct and should therefore be approved.
In any case, please ignore this edit. Polygons cannot be moved from within Google Maps, where this edit comes from; it is an error coming over from Maps where only a point is visible and someone has tried to move that. The issue is known and being worked upon.
