ERP 9 Eliminate Cycle Count Periods

We have several Count cycle periods that have not been counted. How can I delete them?

In e10 we can delete them Cycle Count Schedule Maintenance on the periods tab.
We can also cancel cycle counts from Count Cycle maintenance.

Is there a way to de-select parts? I cannot delete a schedule from Count Cycle Maintenance because parts have been selected. I cannot delete the schedule because Cycle cycle periods have been selected.
