Categories dropdown with all values selected using wp_dropdown_categories

Add this parameter:

'select' => false

The solution is in the WordPress Codex Function Reference for wp_dropdown_categories:

The default value for the selected parameter is 0, but this can cause a dropdown with all terms marked as selected. To fix this, set the selected parameter to false, rather than 0.
