I have the following problem and I don't think this is the correct behaviour :
(Using CB 1.5.2)
When I create a space, convert it into a community, apply a permission scheme, everything looks good.
Then, if I want to rollback from the community to a simple space, I click on the "Remove community settings" link in the space admin.
I still have permissions set from my permission scheme when I created the community. If I want to disable a group from viewing the space, and then click on "save", the group remains in the permission as if it was still linked to the permission scheme, and there is nothing I can do to remove the permission. The only way I found was to create a new permission scheme with no permissions inside (no view, edit, just admin), convert my space to a community using this permission scheme, and the permissions are set correctly. I can then remove the community settings to have a simple standard space.
Do you have any clue about this odd behaviour ?
Thanks a lot.
