Cannot select default ward

For about a week, I've tried selecting the Default Ward when on champion ban / select. In some cases, the icon will show I've picked the Default Ward, but won't display that Ward ingame, instead displaying my Chicken Ward from 2018 April Fools. In other cases it won't even let me pick Default Ward, and chooses another completely random ward. I'm not 100% sure if other people get this bug, but I absolutely cannot pick the Default.
