Lens flares not working in a local 2 player game?

Hey guys! I was having a problem where lens flares are being rendered within my viewport and in single player mode, however, as soon as I add a second player the lens flares no longer work? Is this because of engine restrictions? Is there possibly a way to enable these? Below I have attached a screenshot that shows my issue. As you can see the lens flares on the left are not being rendered. Any advice is welcome. Thanks a lot!
