Task Gantt Error

Created a task: Task A
Added “Depends On” link to Task B
Viewed in Gantt chart, and shows link between Task A and Task B
Deleted “Depends On” link to Task B (no task remaining)
Viewed again in Gantt, still shows link Task A to Task B

Tried other projects and other tasks, all acting the same. Only way to remove the link is to remove the task.

Continues here Task Gantt showing incorrect Depends On Task information
