Append Data from Merge Arrays on Googe Sheet

I want to add rows to a Google sheet from three merged arrays. Each array gives me the following collections:

This is my Google sheet structure:

The problem is, I am only getting the first collection on the Google sheet. How can I get the other two collections on the Google sheet in the next rows?

@FBS_integrations add an iterator between Set variable and Add a Row.

Also, you probably don’t need to create JSON and set variables. You need an iterator between the Array aggregator and Google sheet.

This is the entire flow:

The first array brings LINE ITEMS
The second brings DISCOUNT CODE
the third brings SHIPPING LINES

I needed the JSon to organize the aggregator. I just do not know why the collection is not appending on the Google sheet.
