Schema is not aligning data from dataset correctly

Not sure how this works,

I created a schema for a JSON object. The schema will have a nested structure and then in it., will be a lost of objects(again nested).

As you can see, from the datasource, I should be getting 3 JSON’s only. I seem to be getting some random number of JSONs.

Please assist.

This is my Schema: https://www.mockaroo.com/schemas/223671

also my dataset is attached
