For example: I want cancellation date 2 on 100%, but that is not possible. I only can insert 99%.
The answer for this is: It is not possible to add at period 2 100% because Eventure automatically calculates a third period.
After the second period untill the conference, the cancellation fee is 100%.
If you have only 1 cancellation fee, you have to insert both the periods with the same data.
