Why dual_gap was not raiting map?

Today i play dual_gap but its tell me its not raiting map

the map 'dualgap fix adaptive' is not rated, it didn't credit cookienoob for the adaptive script, or the original authors (kd7bh, biass, etc), so that might be why. It also may be unbalanced.

Its look like need add marker in faf client for identify its ranked game or not... Or give me tips how i can understod its ranked or not ranked game.
