Editable document error

The editable PDF document is transferred to the system. When a change is made and the document is requested to be saved, the document created with Aspose.PDF has no editable feature. When the code is analyzed in debugging, when the “WaterMark” feature is added, it is seen that the editable property of the document does not occur.
I attached the original file and corrupted file. We are using Aspose.PDF 20.6 version. Thanks.
