"Project - Edit Opportunity - All" or "Project - View Opportunity - All" are granted through a Group to the users. What are those access rights for and why the users get them?
The following 2 access rights are deprecated and not longer Active:
"Project - Edit Opportunity - All"
"Project - View Opportunity - All"
They were for an old functionality for Project Opportunities. We don't have Project Opportunities anymore.
Access right "Project - Enable Opportunity" is not deprecated and still Active.
The deprecated access rights are not displayed in the Group because in the tables they have columns IS_ACTIVE=0, RIGHT_TYPE=SYSTEM and GLOBAL_RIGHT_TYPE=SYSTEM, so you can not remove them via the UI. The recommendation is create a new group and deactivate the old group.
