Why are items my timeline sorted randomly?

In some cases, the sorting of items in a timeline can be different than the sort given in a clock list ( Station > Clocks).

All timeline items are scheduled based on the duration of this item. Make sure every clock item has set up a length. In some cases, items may have a length of 00:00. In that case, the scheduled items conflict. They will be scheduled at the same time and sorted randomly.
