Guest user still can view buttons that should be hidden
I have a task with visibility to All Users. Guest user can view the task and leave comments, which is perfect. However, guest also sees a panel of buttons that should be hidden. Screenshot attached and panel highlighted in red. 
Guest user cannot do anything with these buttons, permission is denied, but it should be hidden, just like here on Intellij's youtrack board:
What am I doing wrong? My youtrack is deployed on EC2 instance, version:

Could you please post here, which rights does guest user have?
Global Observer only.
What is the permissions set?
Read Issue, View Voters, CRUD comment, Read work item
Could you please grant the following permissions:
These permissions are already set.
Any updates on the issue?
Sorry for the delay in answering. Did you try only the permissions that I've wrote to you?
Worked like a charm. Thanks a lot. As it seems, Write/Delete rights for a comment causes the issue.
