Maybe I'm misunderstanding your use of addr:street and addr:place -- but 
I note on https://wiki.openstreetmap.org/wiki/Key:addr:place that there 
is an explicit statement that:

> No object should have addr:place=* and addr:street

Also (just checked, as memory like a sieve) JOSM complains if you add 
both addr:street and addr:place.

Cheers,
Neil
