Hello,

To reproduce:
1. Place an UltraGanttView WinForm control on a Form and run the project.
2. Insert 2 tasks leaving the default values.
3. In the predecessors cell of the first task type 2SF.
4. The first task is pushed backwards, which is the correct behavior we are expecting.

5. Now stop the project.
6. Add a UltraCalendarInfo control and set its TaskWorkingHourMode to AutoAdjust.
7. Attach it to the GanttView control, so it will use the UltraCalendarInfo control we just added.
8. Run the program and repeat steps 2 and 3.
9. The first task remains in its place and is not pushed backwards.

Thanks is advance
