This is by design if resources allocated to the task are allocated to the task at 0%.
Check to see if any resources assigned to the task are allocated at 0% in the project in Clarity for the date the project is exported to MSP, as that is the allocation pulled to the Units field for the task in MSP. If the allocation is 0 for the resource, the ETC will be deleted for the related assignments with tasks using Fixed Unit and Fixed Work task types, as the resource doesn't have any allocation to work on the task.
