I’ve actually never used array_rand before so I did some testing. Basically what I found was that no matter how many items you want returned, the keys are always returned in order. So it you pick 3 of 5 you might get 0, 2, 4 but never 4, 0, 2. So when selecting the 5 of 5 it will always return 0, 1, 2, 3, 4
shuffle is what you’re looking for
$repeater = get_field('contributors_grid','option');
shuffle($repeater);
