I don't know what has happened but now it works. I had the old query in
Fuseki GUI so I'm sure I didn't change anything.

I cannot reproduce it:

sparql --data test.ttl --query test.rq
Result:

Do you have named graphs or something? I mean, is just one column
empty or the whole resultset?

Not Jena question but hope someone can help. I have two columns with
always equal amount of rows. How can they be combined into one column
(variable)? This method doesn't work (example has different predicates):
select ?s ?pl_al
where {
?s skos:prefLabel ?pl .
?s skos:altLabel ?al .
bind(concat(?pl, ?al) as ?pl_al)
}
