    hi @christian_feise welcome to the community. I have your process on my computer. So after a quick inspection I see that your Filter Examples operators do not have any parameters; you need to put something there.

    As for merging the output (if that's indeed what you want), you just need to put either an Append operator (if all your data sets inside are exactly the same) or the Union Append building block (if they're not all exactly the same) after Loop Values. Then you can Store.
