Best,

Thanks so much Dereckson, we have the control of the account again.

Sorry for the delay.

1. When you open EV everything is normal editing
2. Using the button to Add Categories you add some of them, the query about existing categories function normally.
3. You choose categories and then Save and close the window
4. The categories does not appear in the saved article

Thanks for the notice, @MarcoAurelio!
I'm adding some details :)
Thanks!
