Scheduling conflicts reporting completely broken

Steps to reproduce:
1. Create a scheduled event
2. Create another scheduling event that overlaps with the one created in step 1

Actual Results:
The "Next" button is greyed out, a message says that there is a conflict.

Expected Results:
The "Next" button is greyed out, a message says that there is a conflict, the conflicting scheduled events are listed.

Workaround (if any):
Trial-and-error until the "Next" button is not greyed out anymore
