Also, when inviting someone else into a group, they sometimes appear as "unnamed" until the screen is refreshed. I think it's for a similar reason as this issue.

Before:  After: 

- Moved show_types change into the setup_problem_list function - Replaced zip with an annotation - Fixed inconsistent padding due to the in-contest types table header not having the "types" class

New Screenshots: Before changes:  With types disabled, after changes  With types enabled, after changes 

Ready for re-review
