Wake Forest Application Fee

I applied to Wake Forest using the Coalition application, and that application was free. In addition, I also had a fee waiver for my Coalition applications, but it did not matter at the time since the Wake Forest application on Coalition was free. However, on the Wake Forest portal, one of the checklist items says that I need to pay the application fee. Is this fee required for all applicants? If so, why was there no fee on the Coalition application? And if this fee is required, why would I not be able to use my Coalition fee waiver?
