Nordic HRM App keeps reporting data when HR sensor is removed ??!!

Hi experts, I'd like to know if it's normal when the HR sensor is removed from ear, but the HRM app keeps reporting the same heart rate data w/ the last value , is it possible to stop it at final and not repeating it ?

thank you

My peripheral is a BT earphone with heart rate sensor, but let's make it simple. If I stop sending HR data to Nordic APP (HRM from nRF Toolbox) but still be connected, will APP keep repeating the heart rate with last HR value? Is it normal ? I've tried both iOS or Android based smart phone , but both will keep repeating the last value even in my code , I forced to stop sending the HR data.
Thank you
