I don't know if that helps but DynamicPageList3 gets the right version
Maybe it has something to do with DPL being pulling data instead of the source page pushing it
As a user I would not mind if I had to start some kind of push job to get the correct version, instead of the refresh being made automatically at saving

I install on another wiki Semantic Mediawiki and have a similar problem
In Semantic Mediawiki the data does not disappear but the latest is seen, not the approved one
For what I can understand it is already known for SMW maybe the problem has the same origin ?
