selected refinement in dashboard is showing in other dashboards from same dataset (Orders)

Dear community,

we have created several dashboard as a copy from the Orders dashboard.

The page URL's are different

URL of the original Orders dashboard is pcc-orders

URL of a personalised orders dashboard is pcc-orders-tatjana

URL of another personalised orders dasbhoard is pcc-orders-arjan

A refinement selected by Tatjana is shown in the orders dasbhoard of Arjan and the original orders dashboard and vice versa.

We are on Command Centers V3.

Is this a setting I can alter or is this standard?

Thank you.
