OP here. I figured it out (or at least a workaround). What I did was - in the HTTP Request module, I unchecked the box to Parse JSON, which is what created the "Collections within an Array" structure.
I then took the raw JSON and passed it to a Parse JSON module, which then converted the JSON into bundles instead of collections. From there, I was able to iterate thru the bundles as desired. I can mark this one solved now, but please feel free to offer other ways I could have accomplished what I'd wanted.
Thanks!
