How to Edit No. of Lessons (Activities)

[JSR]

I've been using FET for a month now.
Once I save a lesson, I can't seem to edit the number of lessons (Split), or the 'Consecutive' option. The Split option is greyed out.
If my lesson should have 5 lessons per week and I accidentally save it with 4, how do I edit it?
If I save my lessons with the 'Consecutive' option selected, how do I edit to deselect that option?

This is written in the Help dialog there. Consecutive goes to the min days between activities constraints, split cannot be modified but by removing the activities and adding them again.
