Your environment

3) If you filter by format
or
4) Filter by organization and format
or
5) Filter by category and format

Expected behaviour

3. I expect to see al the dataset labeled as those specified in the format filter
4. I expect to see all datasets related to the chosen organization whose format is the selected one
