Set Bookmark Content - The range cannot be deleted

I am attempting to set the bookmark content of a Word document and receiving the following error. Any ideas? I’m happy to provide further information if needed.

UiPath v20.4.3

Source: Set Bookmark Content

Message: The range cannot be deleted.

Exception Type: System.Runtime.InteropServices.COMException

RemoteException wrapping System.Runtime.InteropServices.COMException: The range cannot be deleted.

Edit: In Word, this error only occurs with legacy form elements.
