problem met after querying fuseki

Hello, everyone,

I have met a problem with fuseki. After publishing my data stored in the
TDB folder on the fuseki, the query select * where {GRAPH ?src {?s ?p ?o}}
, I have got an almost empty table with many rows, as showed after:

SPARQLer Query Results
sposrc"1" ^^<http://www.w3.org/2001/XMLSchema#integer>"1" ^^<
http://www.w3.org/2001/XMLSchema#integer>"1" ^^<
http://www.w3.org/2001/XMLSchema#integer>
which means that there is result but they are not shown. And when I try to
write all the data in the TDB to an owl file, I have got a file with the
required data. Is there anyone having some ideas that why this happen?
Thank you very much.
