When I try to modify an existing Document Template by adding an additional line, it will not save the data. The View and Type columns both will automatically be emptied to NULL whenever I tab through the columns and try to move on to the next line. See the attached video recording in DropBox https://www.dropbox.com/s/4qzhyhedkialv6g/acumatica_document_template_null.mp4?dl=0 as well as the screen shot.
