Removing contacts in Spark 2.0

Maybe I’‘m just overlooking something here, or maybe this was overlooked. How can I highlight say, 3 users, and delete them from my contacts/roster? the right click -> remove from roster function is only available when selecting one person. Also, shouldn’'t the delete key do the same thing?

What I am specifically trying to do is remove all my MSN and AIM transport contacts, then re-register to hopefully have them re-added. Pandion did some crazy sorting on them and when I tried out Spark, the groups adn usernames were messed up.
