I cant get this to work properly. I have a person or group field on a list and at the end of the workflow, I want to clear the field. I'm using the 'Set Field in Current Item' action currently to set the field to a blank variable. This seems to only partially remove the user entity from the field though as the edit form is broken for the specific item when the workflow has ran. I can also see on the display form that the field still contains some information. Any help on how to do this would be appreciated.
