Not sure if I'm using the correct terminology to describe this. I've configured a custom field as:

"alienexplosive:task-type": {
    "name": "Type",
    "type": "select",
    "search": true,
    "options": {
      "alienexplosive:issue": "Issue",
      "alienexplosive:todo": "Task",
      "alienexplosive:requirement": "Requirement"
    }

However, in my recent activity window I see such entries as:

david changed Type from alienexplosive:issue to alienexplosive:todo on T24: Receive RDM over BLE.

I expected to see:

david changed Type from Issue to Task on T24: Receive RDM over BLE.
