Task Name returns null from REST API

When querying the Task API we are seeing the Name property returned as null in some cases. We are calling the engine-rest/task endpoint with the following body:

{
    "taskVariables": [
        {
            "name": "eligible_users",
            "value": "%a28509%",
            "operator": "like"
        }
    ],
    "processVariables": [
        {
            "name": "order_lock_until",
            "value": "2019-07-25T21:29:10.002311",
            "operator": "lt"
        }
    ],
  
    "unassigned": true,
    "followUpBeforeOrNotExistent": "2019-07-25T21:29:10.002+0000"
}

The response contains many of the same Tasks, some with a Name, some with null.

while modelling your bpmn did you configured the taskname?

Yes. Sorry I didn’t include that originally. All Tasks have a Name. The oddest thing is that some queried Tasks return the Name while some do not.
