Adding a 'response' to a server action repeat breaks the repeat

Not sure if bug, or intended behaviour… Need some advice:

I have a form that is sending 2 arrays of information to a server action.
The server action loops through the values with a ‘repeat’.

Everything works as expected, however when I add a ‘Response’ it will only perform that repeat action one time.
When I disable it it’ll repeat the correct amount of times.

It seems like the ‘response’ is telling the server action that it’s done?
Is there a way around it? I want to display on the front-end that the form submit has failed or succeeded.
