This popup only appears on accounts that haven't completed Sprwt's "Go Live" setup step yet — once your account has gone live, this check is skipped entirely and the popup won't show again, regardless of your fulfilment-day setup. During that pre-launch window, it means your active kitchen location doesn't have any weekday configured as a catering fulfilment day yet (set either via the Catering Fulfilment Days toggle grid on the Catering Settings page, or on the location's own page under Kitchen Locations). The popup can't be dismissed — click Setup Fulfillment Days to go to Kitchen Locations and turn on at least one weekday, then return to build the menu.
