Welcome to the Make community!
In that case you might need to use an Array Aggregator to prepare the entire array of category items instead.
Use the parent map toggle on the Tracking field.
Mapping a Specific Structure Into a Complex Field
If you have an array of collections, in programming terms, this is called an array of objects, or an array with non-primitive data types (“complex”).
The Array Aggregator module is very powerful because it allows you to build a new complex array of collections that matches a later module’s field to map multiple items (collections) to it. Such fields initially would allow you to manually add items, but you can toggle the “Map” switch to the “on” state and map a whole array into a single field.
This is done by selecting the “Target structure type” in an Array Aggregator module.
As you can see from the above example, the “Map” toggle on complex fields are used when you have an array variable (like from an array aggregator). Other combinations of modules may also allow you to generate an array that matches a future field’s array structure, like “Aggregate to JSON + Parse JSON”, or “Create JSON + Parse JSON”, but this is an advanced topic.
Question: Are you mapping your array into a field that accepts more than one item/collection?
Example
Here is an example of how your scenario could look like to build the “Tracking” array:
This is just an example. Your final solution may or may not look like this depending on your requirements and actual data.
For more information, see “Mapping with arrays” in the Help Centre. You should also do the Make Academy, which also covers the use of Iterators & Aggregators.
Hope this helps! If you are still having trouble, please provide more details.

P.S.: investing some effort into the tutorials in the Make Academy will save you lots of time and frustration using Make!
