Facebook Creators Studio: I can't create any instant article style

Question

i have a problem adding styles to my Instant Articles. before I created the styles from my facebook page but now they moved everything to creators Studio. I'm in the process of approving the use of instant articles, but I can't create a style, it gets stuck when i am trying to create a style. I have seen videos where the process is a little different because the default style is created first, but in my case it goes directly to the editor without creating the default style where it gets stuck.

In my case goes first to the editor

this is supposed to create a list first with an element and then pass to the editor. any idea?
Thanks for your time
