When turning on the delete and reset change order links, I would get an error during ajax communication.
Looking in the apache logs, I see this:

The important error was:
Message: Module Kernel::Modules::AgentITSMChangeDelete not registered in Kernel/Config.pm!
I fixed this by going in and looking at the module registration inside the admin:SysConfig:ITSM Change Management:Frontend::Agent::ModuleRegistration
In this area, you have the additional options to load the modules.
This will work for an error pertaining to Module Kernel::Modules:: not registered in Kernel/Config.pm!
FIXED: Error during ajax communication
