When attempting to delete an Alternate Schedule in Assign Work Schedule the schedule disappears

In PeopleSoft 9.2, When attempting to delete an Alternate Schedule in Assign Work Schedule the schedule disappears.

In order to delete this, you must be in Correct History. After clicking on Correct History, the Alternate Schedule (along with the alt schedule and primary schedule tabs) disappear (please see the attached screenshots). After fully exiting HCM and going back into Assign Work Schedule, the Alternate Schedule is still there (and the alt schedule and primary schedule tabs are back). We are unable to delete the Alternate Schedule. Is there something wrong with our access?
