Customized submit varieties not exhibiting within the admin menu on manufacturing, however exhibits domestically

The issue I am going through is:

Domestically:
It exhibits all three customized submit varieties within the admin menu

Manufacturing:
It exhibits solely the primary two customized submit varieties within the admin menu

Has anybody else encountered this drawback? Can somebody level to me the place I am going fallacious? I am unable to determine the issue. Thanks.
