When creating a new document in the New Document dialogue, InDesign (17.4) is allowing a impossible column gutters (Page Size: 8.5"x11", Columns: 1, Column Gutter: 12"). The Margins and Columns dialogue will prevent this from happening, the New Document dialogue will not. This causes issues when attempting to change files later using the Document Setup dialogue, even after the Column Gutter is adjusted in the Margins and Columns dialogue.
