Date Constraint Adding and Deleting Nightmare

Hi,

In gantt view, i like to move times of tasks, but i find that i am adding date constraints when i don't need them and getting rid of them is extremely difficult if not impossible. Even when i remove the dependencies the date constraints are still there. I even have date constraints floating on their own in middle of gantt see below.

One way to remove them is via export/import through excel but that has a bunch of its own issues as export/import strips certain data not exported to excel (another topic of discussion).
