TM1637Display.h problems

Hello i have a problem with my code:
The most in lines as the second minutes line overwrites the hour line and i can set up only two digits hours or minutes:

 if (display.update()) {
  display.showNumberDecEx(timeClient.getHours(),0b01000000,false,2,0);
 display.showNumberDecEx(timeClient.getMinutes(),0,false,2,2);
}

  pixels.show();
  delay(7);
  }
  blue_light();

}

void display_cuckoo(){
flash_cuckoo();
delay(2000);

}

the second one is overwriting the first one and I cannot use hours and minutes at the same time, both commands used seperately work

I did it like this but can't find my old program.

// Create an  unsigned int variable:
        unsigned int disTime;

//Get the current hour and multiply by 100:
      disTime = 100 * timeClient.getHours() + timeClient.getMinutes();

// If the current time is, say, 21:43, disTime should be 2143.
// Then send disTime to display:
    display.showNumberDecEx (disTime, 0b01000000, false, 4, 0;

You may have to play with the "false, 4, 0".

EDIT:
Oh phooey, just remembered the problem when hours = 0 but can't remember how I got around it. Maybe it will come to me in my sleep and I will pass it along (if I wake up). You can probably figure it out yourself. Good luck.

Thanks this is what I wanted.
Its working for now and now I only need to think about the 0 hour problem.
