Adding measures to a visual with data from 2 data sources

[Simon125q]

Hello, I have 2 tables connected 1-1 in both directions, when I add data to a visual table where the connecting key is preasant everything is alright. 

But when i add a measure to it, it looks like the connection between those tables becomes inactive:

My first thought was that it was cause of the measure:

I was looking for some solutions online or similar problems but couldnt find anything. Thanks for help in advace.
