By doing the renewal I do not get the package back to purchase, why?

Evidently the lesson package is not configured or not configured correctly.

Navigate to Configuration →Packages for courses delivered on a monthly, lesson and hourly fee basis from here verify that the package of interest is by number of lessons/hours or months consistently as set in the Course Reference and that the cost of the individual month/lesson is in line with that set within the course. Here is the guide to creating a new package.
