Model trained via API refers to non-existent class labels

Here’s something I just noticed. If I get some info about a project I’ve made using the Roboflow site:

We can see that project.classes lists the number of ‘lola’ instances:

But if I do that again for a project I’ve created using the API

(https://api.roboflow.com/iadt/lola/4?api_key=****nocache=true)

The classes are empty, despite having added 12 annotated images with the class name ‘lola’ to this one too:

Could this be the reason for the random coin-related class names?
