After sending my package I am required to have properties related to a "Game" when it is an "App"

Question

Hi, I am trying to publish an App for MS Store through the Partner Center.

It's my first time and the experience has been quite frustrating. After setting up the Dev account, paying and performing different actions, I'm at the step of performing the "Submission".

The problem I'm having is when making the "Submission".

In the Properties step, I fill it in before sending the package in the "Packages" step. When I fill it in everything is ok, and the step is confirmed in Green. What happens is that when I upload the package, the "Properties" step is incomplete again and the form asks me for information related to "Games" (Genre, Game Settins, Display mode...) But my package is a desktop app, not a game. What's worse, even though I try to fill in these fields, the Save action doesn't work and no form validation error is displayed.

Does anyone have any idea why or where to go from here?

On the other hand I have tried to submit a ticket from the "Help+support" section of the Partner Center but it sends me to MS Support, and the latter back to the Partner Center, literally, I don't even know how to put a ticker or ask for help.

Thanks :P
