You need to create action filters from the sheet in dashboard 2 to the sheets in dashboard 1 also.
If I create action filters from the sheet in dashboard 2 to the sheets in dashboard 1, what i'm getting is that first i'm jumping between dashboards and i am filtering the data.
I do not want to jump between dashboards and i do not want to filter my worksheet by country, i only want to undo the highlight when i clicked in the first dashboard and highlight the country i've selected.
Actually, it happens in the same dashboard, and its easier to explain.
If i filter by Country 1 and then i change the selection to Country 2 trough quick filter (sync) the graph by country appears with Country 1 highlighted.
