I believe you can post this code in your functions.php folder. This has worked for others so it might be worth a try.
add_filter('__is_home' , 'home_check_fix');
function home_check_fix() {
return ( (is_home() && ( 'posts' == get_option( 'show_on_front' ) || 'nothing' == get_option( 'show_on_front' ) ) ) || is_front_page() ) ? true : false;
}
I put it under my custom menu functions.php – but did not work
It could be a bug, have you tried rearranging the order of the pictures in the slider? I know that sounds pointless, but in the case it is a bug that can be successful.
