Unable to change charge date on recurring gift

I'm having trouble changing the charge date for recurring gifts in my Click & Pay Suite. The system seems to be preventing me from modifying the billing cycle. Steps to reproduce: 1. Go to recurring gift management 2. Try to edit the charge date 3. System shows error or doesn't save changes Expected: Should be able to modify charge dates Actual: Changes are not being saved This is affecting our donor management process. Any help would be appreciated!
