SPARQL interface from FDP web client not displaying the correct results

[inuites]

Describe the bug
SPARQL interface from FDP web client not showing all results from the default query.

To Reproduce

1. Go into the SPARQL interface of the web client FDP. Ex: https://fair.healthinformationportal.eu/search?isSparql=true
2. Click "search". It will show only 25 results sorted alphabetically (from A.... to C....)
3. Modify the query by changing ASC(?title) -> DESC(?title)
4. Click "search". It will show 25 results (but different from point 2. ) sorted alphabetically (from U... to C....)

Expected behavior
It should show 50 results instead 25 because LIMIT 50 in the query and because there are >50 metadata hosted under this FDP instance.
This doesn't happen if you do the default query but you change ASC(?title) -> ASC(?rdfType)
Then it shows 50 results all the time

Thank you
