Hi Oscar,
Thank you for your interest in Syncfusion Products.
EssentialDocIO will not update the fields automatically.As a workaround could you please create the macro for any one of the word document with the following code snippet.
Code:
Sub AutoOpen()
Dim aStory As Range
Dim aField As Field
For Each aStory In ActiveDocument.StoryRanges
For Each aField In aStory.Fields
aField.Update
Next aField
Next aStory
End Sub
For more information regarding the automatic updation of fields, please refer the following link
