If you see a multitude of assets on the Calculus Map, instead of just the single asset of which you are viewing the detail dashboard, adjust the radius setting.
Open the widget configuration panel, set the Radius in meters field to a lower value, for example 1 meter. This ensures that other assets, located outside this perimeter, are not displayed.

Don’t forget to Save the settings.
Attention!
To make changes to a dashboard, you must have the user right DashboardManagement.
