BE 2014 - Job scheduled even when status is unscheduled

I imported job sets from 2010 that included Full and differential jobs. I'm changing our backup procedure because we're starting to use a dedup device, so I want to keep the diff job settings but not the full.

I tried setting the full job to unscheduled, but it still shows up as scheduled. Then I tried to set the schedule reccurance for years and set the start date to several months in the future, but it still wants to start on the next weekday listed. I can delete the whole job, but then I'll have to recreate the diff job.

I've attached a screenshot. Any ideas? Of course, I can blow away the whole job and recreate the diff, but would rather fix if I can.

Thanks.
