Version 4.8.1 allowed editing of existing scheduled tasks. For example, you could disable or enable a task to run as scheduled. In the latest 4.8.2 version, it seems the only way to edit a scheduled task is to export / import scheduler definitions. Is this correct?
This is unfortunately a regression (missing UI icons). You can follow this issue - this should be fixed in the upcoming 4.8.3 version. In the meantime your workaround is correct.
