Error seems to have occurred when trying to rename a previously-created schedule (possibly to something that was the same as an existing schedule???)

Schedule name change saved, but the frontend was showing negative numbers.
User tried editing the entire schedule, but it didn’t work (presumably the cause of this issue).

after clicking refresh on classclock (possibly frontend? not sure) it seemed to work after that

needs replication
