[OCS API] Wrong downloads count for an item

I’m trying to use OSC API to get the downloads count of my item published on the Pling store.

The item id is: 1875687

I’m using the following url:
https://api.pling.com/ocs/v1/content/data/1875687?format=json

In response I get “5197” downloads:

But the Pling store page shows the downloads count “4315” for the last and only available file:

At first I assumed that the API response counts all-time downloads including the archived files, but the returned number doesn’t correspond. I checked a few other items from the Pling store, and the returned downloads value always doesn’t correspond, despite all the other information being correct (publication name, version number, comments count, etc).

We are looking at this and correcting it if necessary, as we are currently working on the API.
