By removing the third action on your dashboard (it's called Filter 1, with QT-P15 as the source and Estado as the Field), clicking on a point on a map will 'gray' out the other points. Having this filter on the view, makes the view more specific and thus, Tableau thinks they want just the data for the specific point (and for only that point to be shown on the map).
In terms of the totals, Tableau will never show just the total. It will either show all the points on the view, a single point or other specific points that are highlighted.
I hope this helps!
Thank you very much for your answer. I have the updated the viz and it seems to be working just fine.
Again, thank you very much.
