osmconvert -filter gives back a pure non-sense result

did a request with the following

in order to filter & gather the schools - but believe me: the results in the cal-sheets were looking like pure none - sense...

update: thanks to someoneElse i have corrected the code for the request regarding danish shools:

./osmconvert denmark-latest.osm.pbf -o=denmark.o5m
./osmfilter denmark.o5m --keep="amenity=school" -o=denmarkschools.o5m
./osmconvert denmarkschools.o5m --csv="@id @lon @lat name addr:street addr:housenumber addr:city website email" --csv-headline -o=denmarkschools_3.csv

now the results are a bit better!!!

end of the update: see the code:

denmark

./osmconvert denmark-latest.osm.pbf -o=denmark.o5m
./osmfilter denmark.o5m --keep="amenity=school" -o=denmarkschools.o5m
./osmconvert denmarkschools.o5m --csv="@id @lon @lat restaurant:name addr:street addr:housenumber addr:city website email" --csv-headline -o=denmarkschools_2.csv
--csv-headline -o=denmarkschools_2.csv

luxembourg

./osmconvert luxembourg-latest.osm.pbf -o=luxembourg-schools.o5m
./osmfilter luxembourg-schools.o5m --keep="amenity=school" -o=luxschools.o5m
./osmconvert luxschools.o5m --csv="@id @lon @lat schools:name addr:street addr:housenumber addr:city website email" --csv-headline -o=luxschools_2.csv

hamburg: ./osmconvert hamburg-latest.osm.pbf -o=hh-schools.o5m ./osmfilter hh-schools.o5m --keep="amenity=school" -o=all_hh_schools.o5m ./osmconvert all_hh_schools.o5m --csv="@id @lon @lat schools:name addr:street addr:housenumber addr:city website email" --csv-headline -o=all_hh_schools_2.csv
