To add a row of chain maille, you add 5 rings, one to each column. 3 of the rings will be added as closed rings and 2 will be added as open rings. None of the rings sit perfectly flat, each ring has a raised edge. Note the position of the raised edge in columns 2 and 4, the raised top part of the ring is at the front - shown with red dots. In columns 1, 3 and 5 the raised edge of the rings is at the back - shown with blue dots. If your rings don't look the same simply turn the chain over.
