The problem concerns two ads using the same schedule, when they should not.
Should be: Ad A – 01.04.2017 – 30.04.2017 Ad B – 01.04.2017 – 31.10.2017
But is displayed as: Ad A – 01.04.2017 – 30.04.2017 Ad B – 01.04.2017 – 30.04.2017
Saving either ad saves to the schedule, which is referenced by both Ads
Although I was able to fix it by inserting a schedule for Ad B in _adrotate_schedule and referencing that schedule in _adrotate_linkmeta it would be nice to know why this is happening and if we can do something to avoid it in the future. Both banners where added independent of each other.
