I dont want a key field in my visual. Next to that. I think that Bridge Tables should be hidden tables. They are there so i can avoid N:M relationships.

Hi @RJOttenheim ,

 

Based on my test, please do not drag the related Key field to visuals:

If you want, you need to use the Key field from the Bridge table , as shown below:

try using single directional and one to many

As i said. Changing directions doesnt work.

Single Directional and one to many is what the picture shows.
