Cross filtering

Hi

I hope somebody can explain to me how it works, maybe i have misunderstood?

The way i understand it:

When applying cross filtering between lookup tables i can consider the tables as one.

I have 4 lookup tables which i have linked (blue circle).

Two of them are then linked to two data tables, so i should be able to choose any filter within the blue circle and it should affect the data tables?

However if i filter by the "Vognløb" (red circle with yellow) it is not affecting my data tables.

How should i work with cross filtering when i have more than to tables linked together?

Thanks in advance.
