Missing database for "Kraken-report" in galaxay eu server

Kraken2 classification was successfully done in the galaxy eu server with no error (Figure A). However, when i tried to view sample report of a classification in Kraken-report , there were no database in the list to select (Figure B). Hence, it is not possible to view the report of classifiecaion done on kraken2. Is there any way to overcome this issue?
