If I remember rightly, in programs like Clustal you can specify where
bootstrap values are stored - node or branch. I can't remember which is
the default way, but TreeView can only see bootstraps in they are stored
using the "non-default" setting. This "could" be the same issue here.

I don't know without a closer look - i'd also need to look at the newick
format definition as to whether this is an "extension" to the format or
if something is just flouting the newick rules.
