Attiny85 and NRF24L01 remote controller not working properly

[sreekanthmp]

With the ATtiny85 (3Pin configuration) and NRF2401, I created a program for a single button remote controller.
When the button is pressed for more than 400 milliseconds, the transmitter circuit will transfer the payload, and after 3000 milliseconds, the attiny will go into sleep mode and close the transistor that controls the nrf24l01 module's power supply.

The issue I'm having is that the tx circuit only sends the payload after the third time button hit, this only occurred immediate after waking up from sleep mode. While wakeup condition tx circuit send payload on each press.

Here is my code ,Kindly let me know if anything wrong in code.

#include <avr/interrupt.h>

#define adc_enable()  (ADCSRA |=  (1<<ADEN)) // re-enable ADC
#define INTERRUPT_PIN PCINT4  // This is PB1 per the schematic
#define INT_PIN PB4           // Interrupt pin of choice: PB1 (same as PCINT1) - Pin 3
