The "Perfect" text, indicating that you achieved maximum combo on a map, is only displayed on Circle-only maps, and is not displayed on any maps that have at least either one slider or one spinner. This is only applicable on CatchTheBeat game mode.
Possible solution is to take the amount of the map's maximum combo from osu!Standard game mode, and subtract it by number of spinners.
