How do I remove the date from a scheduled task?

I mistakenly added a date to a task that I have no needed date for as of yet. In the old version, I could simply take the task and drag it from the schedule back to the role it was under. The new version lacks this ability as the schedule, role, and parking lot are on separate pages. I'm at a loss as to how to remove a date completely and leave it as a reference under a role.
