Partial role list

Hello,
I have a number of roles created using the Members plugin; however, I do not see any of those roles in the settings GD bbPress Attachments settings. All I see are Keymaster, Moderators, Participant, etc.

Any ideas how I get those to show up? Is there a specific permission I need to enable / add to these roles?

Thank you!
