What controls list of Roles in Comment Visibility dropdown?

[Kathy Barton]

Hi, I am trying to update a project created by someone else in a server 6.4 instance of JIRA and I am stumped. The list of Roles in the Comment Visibility dropdown on a ticket is missing one of the key roles for this project and has one that I want to get rid of. I checked another project where this is working and that list seems fine. Can anyone tell me where I can look to fix this? I've tried everythign I can think of and nothing is helping. 

Thanks!

Are you in the role that is missing?  And the one that should not be there?

[Kathy Barton]

I'm in the one that's missing and not in the one(s) I don't want to have visible.

Bother, that rules out what I thought it was.  Sorry, I'm stuck on this one.  I thought it was simply "you can only share with the roles you belong to"

Yeah, I was hopeful when I saw your response but it didn't pan out. This is the "fun" part of managing legacy systems other people designed :)

Yeah, inheriting systems is great sometimes.  But there's always the odd quirk, where someone hasn't documented it.  (Not sure I'd say "legacy" though, as a large chunk of the work I do is moving people from legacy systems on to Atlassian stuff)
