Issue with query parameters for data links inside dashboard panel when linking to another dashboard panel

So I have created three dashboards for Company Department and Employee.
I created data link to All Companies to Department. All Panels show table values.The issue is that when I use data link to link departments to companies it should show filtered values. In the panel in Department Dashboard I can filter. (I have created variable of query type and filtered using each value) When I click on Company the variable is getting filtered. But the table is showing no data. How do I fix this? Any Ideas. Please suggest me.

In query parameter referencing to Department it shows %2F instead of / how do I change it
