Looks like you're using the Classic Designer.
I've been using the new Responsive Designer in O365.
My experience in this case is the original field name will have a prefix called "RelatedList__" and in the left panel the control category is named, "Related List Columns".
So when executing the Assign a Task action, the Task Form is in Edit mode by default.
So any changes made in the Task Form for the Related List Columns is updated in the original item (along with recording the reviewer comments and what you call the Final Conclusion).
Try the new Responsive Designer in O365 for your adjudication form.

I would use the new Responsive designer and use variables to capture the data and save it to the list using the workflow once task is actioned.

I don't believe the Classic Designer has anything to do with this. The reason I say that is because there are 2 other seperate workflows that have similar approval tasks that work just fine. Also, this form is for a location outside of the US and the load time of the responsive forms are awful compared to the classic forms.

Hi,
So other controls are saving and just not these 4 is that correct?
If so, try deleting the controls and then draging out new ones from the List columns section of the forms designer toolbox.

@cjones did you ever get this resolved?

No, not yet. We've tried deleting the controls and re-adding them, but with no luck. Currently we are in the process of just re-creating the task itself. If that does not work, then we will try recreating the workflow...
