I translated a German version of a book in an English version. I copied
for the name index one indexed name from the German into the English
version, but forgot to set back the German (shown by the blue
underline). This resulted in not showing it in the English name index,
and in addition the two same names (which were created in the English
version) were not shown either. Setting back the wrong one solved it.
In my opinion this should not happen. There should at least be a
warning. It is not a serious error, but it took me some time to find out
the reason; therefore I report it.
