Confirming that when I test on butternut and try to place a hold for patron Ramos (99999389066, home lib BR2, pickup location BR3, staff workstation BR1), it defaults to hold pickup location of BR2 regardless of whether the fallback OUS is set to true or false.
If I test with patron Lamb (99999355318, home lib BR2, pickup lib unset, staff workstation BR1), it again defaults to BR2 regardless of the OU setting.
