Error popup in Client when disabling Review Accept/Reject from the App Manager Collection Management screen:
Application Management->Collections->Modify Collection Properties:
Unselect "Reviews can be Accepted or Rejected" on any Collection where it is already selected and hit "Update"
Works fine from "Manage" Collection interface, or when ENabling review accept/reject.

Application Management->Collections->Modify Collection Properties:
Grant required to set Accept or Reject: Always shows "Manage or Owner" no matter what the actual setting is.
You can make a change with the pull down to "Owner" and it will be reflected in the DB and individual Collection Management interface, but will still show "Manage or Owner" when next opened in the App Management Collection interface.

Confirmed the latest commit resolves both issues mentioned in my comments.
