There are 2 Author sort locations,
on is in the book Metadata, The other is a Author right-click (sort) option in the Tag Browser.
Woohoo! OK I fixed UKLG she is now in her proper place in the L's.
So, now my question is why are there two places to edit the author sort and what does the meta data sort do if it doesn't change how it is sorted in the user interface?
I am still working on the peanut butter-toast-flip experiment.
