Thanks RomGuyony. I was able to clear my mailbox by starting and retiring from each race. However, they would still be in my races. My 2015 LMP1 cars were not upgraded as much as them, so I could not beat them. I tried logging in and out, offline & online, everything I could think of. Suddenly they were just gone!! I guess it just takes time. It was 2 to 3 hours after I left the team before they all disappeared.
