Hi @hekl

Thank you for the issue! What is the input data that you are using?

[hekl]

A csv file. I add it here. Taking the url column as its subject entity.
opleidingen_simple.csv

Thanks! I think the issue that you didn't connect the resource (the grey circle) with a data source (the CSV file). If a resource is related to a data source then it will have a different color. As shown in this video.

[hekl]

I have tried in Firefox and Chrome, but I am not able to click the source file radio button.

Did you try it using drag and drop, like shown in the video?

[hekl]

Yes, I did. From your video I see that when loading the csv file the radio button turns orange. In my case it doesn't. The dragged entity like wise stays grey.

But in your case it's blue. There is not difference in meaning besides indicating the different data sources.
