We had a similar issue with NW 8.0.1.1 where there were save sets in the 
savegroup report which appeared as failed but later also as successful.
This has been solved wit 8.0.1.4. But obviously there are still issues with 
these reports.

However, to summarize the size i would never realy on the savegroup report but 
always query the media db.
