You do not see the option save because Team filter is set only for the report, not for whole eazyBI dashboard which is published with a gadget. To make it work:
Go to eazyBI dashboard “Time Trackin Squad Reports” and set Team as common page filter for the whole dashboard (check out the answer with GIF how to do it on Apr '18 ).
More information on eazyBI dashboards and common page filters are in the documentation: https://docs.eazybi.com/display/EAZYBI/Create+dashboards#Createdashboards-Commondashboardpagedimensions
When it is done, Jira dashboard owner will be able to save selected value for common page filter in the eazyBI gadget in Jira dashboard.
I do not recommend creating duplicating reports in eazyBI as it is hard to maintain. Instead, you might want to create multiple dashboards for publishing where users are going to use those reports. For example, create multiple Jira dashboards, one for each team. Then each team can maintain their own Jira dashboard and save the initial selection for eazyBI reports, like, Team and Project, and even add more gadgets with essential information.
