May I know how to fix this issue? why it's happening like this?

This is the code Im using:

#include <Arduino.h>
#include <DWIN.h>
#include <SPI.h>
#include <Wire.h>

#define DGUS_BAUD 115200

#define DGUS_SERIAL Serial2
DWIN hmi(DGUS_SERIAL, 16, 17, DGUS_BAUD);

#define temperature_add 0x61

unsigned char Temperature[8] = {0x5a, 0xa5, 0x05, 0x82, temperature_add, 0x00, 0x00, 0x00};

// Event Occurs when response comes from HMI
void onHMIEvent(String address, int lastByte, String message, String response){
Serial.println("OnEvent : [ A : " + address + " | D : "+ String(lastByte, HEX)+ " | M : "+message+" | R : "+response+ " ]");
if (address == "6500"){
if(String("1")==(String(lastByte, HEX))){
digitalWrite(27,HIGH);
}else{
digitalWrite(27,LOW);
}
}
}

void setup() {
Serial.begin(115200);
Serial.println("DWIN HMI ~ Hello World");
hmi.echoEnabled(false);
hmi.hmiCallBack(onHMIEvent);
pinMode(27,OUTPUT);
digitalWrite(27,LOW);
}
int t=0;
int tf=0;

void loop() {
// Listen HMI Events
hmi.listen();

// // Write data to DWIN display
// if (tf < 998) {
// tf++;
// } else {
// tf = 0;
// }
// t = tf * 1000;

// Temperature[6] = highByte(t);
// Temperature[7] = lowByte(t);

// Serial2.write(Temperature, HEX);

}
