Hi,
I tested with WP Bakery Page Builder (former Visual Composer) and shortcode works for me. Do not forget that it works for for the text/content parts only.
Re-check if you input shortcode in the text mode (not visual). Try to place shortcode parts at the new lines, like here:
[user_role_editor roles="editor"]
Test Post 300 - for editors only
[/user_role_editor]
Builder may replace parts of shortcode in other cases.
