Assistance with assigning multiple permissions on Role Permission Manager

I’m trying to assign two sets of permissions to my Sales Users.

If they’re a creator of an Opportunity, they should be able to Read, Write to it, or even Delete it.
However, if they’re not the creator (Opportunities created by other team members), then they should only be able to Read the opportunity, view it on Dashboard/reports, etc.

Here’s how I have set it up, but it seems the permissions are not working correctly. My Sales Users still see only their own Opportunities, none other. What am I missing?

Given permission is correct but you are still encountering issues, please log out from the current ID and log in again. This can help refresh your session and apply any recent changes.
