Hello Michael (most of my students address me as "Hi John" so I have no intention of insisting on a professorial title!),
Keshav is right that "print E.mwrank()" displays that strong properly, and also that the offending misleading string does appear, sorry. I have just changed the mwrank source code so that in future it will say "found points which generate a subgroup of rank 0" which is certainly better. It will take a while for that to get into Sage though. I'm always looking for improvements in the quality of the output, so thanks.
