Delta.dumb shows the 4:29 departure the departure as only having First Class available. Seat map shows coach seats. Called Delta rep says there are coach seats still forsale.
So buy a FC seat or call and pay $25 extra for the coach seat.
This isn't necessarily a bug. Delta.com will show you the cheapest fare for a particular routing. Sometimes this will be an A fare, which books into first class. A fares are often cheaper than Y, B, and M fares, which are coach fares. Thus there would still be coach seats to sell.
