Did you try reporting that to Alpha Vantage?  That's the kind of thing 
they did respond to on Aug 17 (see 
https://github.com/joshuaulrich/quantmod/issues/176).

Now that I read those messages more closely, it does appear they were in 
touch with anozari sometime in July.  So perhaps it's just me they don't 
respond to.  I was asking how to do things (and suggesting documentation 
and metadata additions), I wasn't reporting on data errors.
