Hi there,
Not sure if this is the same thing, but in your job that you create, you have a date that the job goes into effect. That's all it is...the date the backup would start from. Most of my jobs show in 2008 when BEWS 11D was installed (and carried over when upgrading to 12.5), but in Job Monitor it shows the days on which the jobs will run (GFS policy).
So that is correct what it shows in Job Setup, and nothing to worry about. You could actually set up a job now, and have it run in 6 months time...
Let me know if this is correct or not!
