1 - To go back to the Contracts main dashboard, where you can change contracts, you can select on "All Contracts". 

2 - To Navigate back to the Overview page of your selected contract, please click on the "Contract". 

3 - If you navigated to the single report page from a specific tab, for example IIF, you can then use this breadcrumb to navigate back to that tab.
