Welcome to the Make community!
Simply delete the Text Aggregator module. Aggregators combine bundles, which in your case, are three bundles containing a document each.
You can also learn more about iterators and aggregators in these Make Academy units:

- Importing JSON into a new scenario
- Iterating an array into bundles
- Aggregating an array from bundles
- Iterator and Aggregator use cases
Hope this helps! If you are still having trouble, please provide more details.
