Can't get 'immediately as data arrives' to work (run once does work)

I’ve put a ‘Watch changes’ trigger from Google Sheets in my make.com flow. When I press ‘run once’ and change something inside the Google Sheets (colum K), then trigger works and the flow will sart. Now, I want that the trigger will start everytime I change something inside the Google Sheets (also colum K). I thought I should put the trigger on ‘immediately as data arrives’, but that doesnt work, while it does work when I press on ‘run once’.

How can the trigger start everytime something will change inside ‘colum K’?

Never mind, it only doesnt work when i’m editing the flow. When i leave the editing screen and make a change in the Sheet, then the flow will start.
