Hi wildmaps,

please check your imports better.

It is also a little frustrating when you find dozens of addresses on the wrong side of the street or duplicate entries or addresses that cannot be found locally in the data. I deleted about 100 duplicates that I had already entered here years ago...
Your source seems not to be the best :-(
Example:
There is no
https://www.openstreetmap.org/node/12188318945
and
https://www.openstreetmap.org/node/12188321468
(both housenumber 5a nearby with different addr:street)
or housenumer 10 in the mid of the square: https://www.openstreetmap.org/node/12188319211

best regards
