Multiple Data Security policies assigned to Line manager role for only one section

Summary:

Hello All,

We have given a view and report access for line managers to a section using "Content section access" after changing this we have run the schedule process. But we are still able to edit the section after of give only view and report access. I have manually removed all the "Manage" data security policies from the role. But I have observed that for this section there are 3 data security policies on view and report (Similarly for "Manage"). (Refer to the screenshot below for view and report access)

Is this the expected behavior? Why are there additional data security policies? After running the schedule process all the "Manage" access should be removed. Can you please help me with this?
