Adding a new cycle count to an open schedule

Hi everyone,

I have an open schedule that has a period start: 1/1/2025 and period end 3/31/2025. There are 2 cycles in this schedule and I want to add a third. The 2 cycles are both closed. The option to add a New Cycle is greyed out in Cycle Count Schedule Maintenance and I’m not sure why or how to get around this. I do not want to create a new schedule, I just want to add a new cycle to the existing schedule. Does anyone know how this can be done? Please and thank you!
