Hello @Poel van der, RE (Ron) and welcome to Microsoft Q&A.
I think there is a little confusion here.
Picture #3 is passing the values defined in picture #2 to the parameters in picture #1.
Also, you do not need the values in picture #2 to be quoted. That is taken care of for you.
Picture #4 only happens when the datasets you selected, have been parameterized outside of the data flow. As in the below pictures of a parameterized dataset.
Picture #4 is passing values to the datasets parameters like above, not to the data flow parameters of picture #1.
The interaction between the source/sink settings in the data flow, and the respective dataset properties can get complex very quickly.
