for week-based recurrence schemes, only every second timeslot gets created

When creating a new show with a week-based recurrence scheme, there is only every second timeslot created, while the recurrence scheme is correctly displayed on the Show Info Page. Creating a Wiederholungsprogramm on the same day & time (also with a weekly schedule) seemed not trigger the collision detection. (I tested this on 20/11/23 with the current version of dashboard.aura.radio in Firefox/Ubuntu)
