It seems that you copy pasted the first kiai onto the second kiai and moved it around for every single difficulty.
Doing this much copypaste for sections is really boring for a difficulty since you are basically replaying the same content with the same rhythm all over again, you just flip it around and call it a day, but this affects the quality of your beatmap severely.
I'd suggest you remap those sections to add some variety as it would increase the quality of your beatmap by adding new patterns, sliders, jumps, etc. It gives life to the difficulties!
