Permissions Graphic Editor view is not updated after Changes in List Editor

Current Situation

Carry out the following steps:

• Create a new role
• Click on the new role name to open the permissions tab
• Select graphic editor
• Click on an object with child nodes (e.g. jobscheduler_master) to set the permission
• Open the child nodes (+ symbol)
• Remove a child permission (e.g. execute)
• Change to list view
• Permissions are correctly shown
• Delete the removed permission (X symbol)
• shiro.ini is correctly updated
• Change back to graphic view
• Permissions are not updated, the JSON answer is correct.

Desired Behaviour

When the steps described above are followed the Permissions shown in the graphic editor should be updated to reflect those in the shiro.ini file and those shown in the list editor.
