Deleting Parameters in Report Studio

Before I knew what I was doing, I created two sets up date parameters on the parameter page for a report I created. Now I have to enter the starting and ending dates for the report two times. How do I delete one set of these parameters?

Just check your query and delete the un-necessary filters, deleting a prompt page doesn’t delete the Filters.

But when all the related filters are deleted , the parameter will disappear as well.
