Bulk AI Post Creator cycle time problem.

Why is it that multiple tasks are set to automatically execute in a loop, but the next execution time of the tasks is always modified so that all tasks execute at the same time. I am using the copy function to batch create the tasks after setting up the first one. For example, the three screenshots below are of three separate tasks, and they generate a different number of articles per hour, but the next execution time always becomes the same. This leads to failures when there are too many threads executing at the same time.
