POST request getting back wrong data even though no error is returned

I am using a POST request which returns a value for the total number of results, total_results = 1, (but the result itself, which is supposed to be a marketplace listing, doesn’t load in the repeating group), and yet when I check via POSTMAN and cURL, I get back the correct number of results, which is 47. No error is returned in either case. In both cases, I’m testing the API with an empty string, which, according to the API creator, should return all results (in this case, 47 results spread across 5 pages).

I would appreciate any help.

It is going to be hard to tell what the issue is without more details like images, workflows, API and etc…
