Modx don´t take the url variable "&template=number" for setting default template, it always show the same template ( 2 ) when creating new resource, and breaking some functionality in extras like Collection, and in shortcut buttons in the dashboard.
I check the default_template system setting, and it´s set to 1, check the Form Customization rules, no template set...
As i expected was my mistake, default_template is ok, i desactivate every rule in form customization and the problem fix, so i started one by one activating each rule until i found one rule ( when adding news ) that sets the template number 2 by mistake.
