Hello joe_aro-SP,
looks like your user has more permissions than needed. You could try to remove the user from User Information List (<a href="http:///_layouts/15/people.aspx?MembershipGroupId=0">http://<your_site>/_layouts/15/people.aspx?MembershipGroupId=0)
and grant him/her ONLY read permissions (add it to the SharePoint group with read permissions).
Another options is to create a new permission level (via Central Admin->Manage Web Application, select the web application and choose "Permission Policy"). When creating the permission policy select "View Items" under List permissions.
Create a new SharePoint group and assign the newly created permission policy. Inside the permission policy you could add accounts that could Only view items for the site collection.
Let me know if this one is helpful.
Regards
