Asset Store Tools 4.0.1 - Chaos

I recently updated Asset Store Tools to version 4.0.1 and tried to submit a package. First of, in Package Upload, the listing of steps goes from 1 to 4 and 3 is missing which is either a bug on my side or a slight mistake on Unity's side. (Either way, it drives my OCD crazy). Also, uploading a package (new, in draft format, not an update) simply won't work. No error/success messages and the publisher page seems to have no idea of the actual asset (metadata is there). Any ideas?
