I'm glad you checked those circlips - having one pop out is a very nasty failure mode, and I like to double or triple check them.
Honda's top ring is radiused on both top and bottom edges, it doesn't have a top. IIRC, I haven't seen a top marking on their original equipment rings. The "TOP" on the lighter coloured replacement ring might signify that it is the top ring. I don't like that ring: it seems to have burrs on the top and bottom surfaces at the ring gap. That isn't the kind of finish you get from Honda. If it were me, and I could feel the burrs with a finger-tip, I'd remove them carefully with a light touch of a needle file, then clean the swarf off. However you must hold the needle file flat along the top and bottom surfaces of the ring - don't just file it or you'll chamfer the edges rather than remove the burrs. They should clean up with one stroke, just a few centimetres of total movement of the file, with light fingertip contact pressure. There shouldn't be noticeable file marks on the top and bottom surfaces, just a sort of dull look, except where the burr has been.
