Your English is really hard to understand but I tried my best to catch your meaning!
You problem is due to not in the CONFIG MODE, follow the steps below, please!
1. make sure LOGO of Cross Hair is breathing, whatever is color is.
2. press SHARE+OPTIONS(PS4 platform)keys on your controller to enter CONFIG MODE and the LOGO’s light will be turned off in this mode
3. then, you can use D-Pad Up/Down key for HIP sensitivity and D-Pad Right/Right key for ADS sensitivity.
4. after adjusting, press SHARE+OPTIONS(PS4 platform)keys on your controller to exit the CONFIG MODE.
LOGO of Cross Hair will breathing again!
