When I try to his second effect, that can special summon a fusion material monster with specific name from GY doesn't work with DM of Chaos.
I mean: Dark Cavalry requires DM as fusion materail monster. The name of DM of Chaos became DM when it is in the GY. So I can special summon it from GY, but the effect doesn't work.
How can I fix this issue?

Indeed, the card text says it is treated as DM in the graveyard.
However, I believe that for Ritual Monsters the condition is that they have to be properly ritual summoned during the duel before they could be special summoned.
