BitBucket: Cannot Add User To new Pull Request when multiple groups exists

[Bradley Harrison]

I have missing users when trying to add a PR

The Repository has several groups assigned WRITE

Group A:

User A

User B

User C

User D

User E

Group B:

User C

User D

User E

User N - Z

When selecting users, most users in `Group B` pull up, no users in both group A and group B show up.  but what baffles me most, is for some users (in Group B) User S and T will show up, but not for me.  When I remove Group A from the REPO WRITE, ALL users are visible.

Any ideas?  other than "Bitbucket does not work well with multiple WRITE groups with people coexisting in both groups"
