Core ML Model Deployment - Add First Model

I am trying to deploy our first Core ML model through the dashboard at https://ml.developer.apple.com/. Immediately after I go into the site, I get a message that reads "Your request is invalid.".

I click "+" to add a model collection, I enter a collection ID, a description and a single model ID and then tap on "Create". I get a message that reads "One of the fields was invalid.".

I have tried changing the IDs and the description, but there is no way to make it work.

I have been trying this for hours. Could you please guide me on how to make it work?
