TELEMATICS 3.5" TFT Touch LCD Shield SKU: DFR0387

recently i order a touch lcd from dfrobot and while im trying to print a sentence using dfrobot code example

its show me only the first letter from the sentence

this the code im using to print

#include <Arduino.h>
25 #include <SPI.h>
26 #include <MultiLCD.h>
27
28 LCD_R61581 lcd;
29
30 void setup(){
31 lcd.begin();
32 lcd.setFontSize(FONT_SIZE_MEDIUM); //set font size
33 lcd.setColor(RGB16_RED); //set strings color
34 lcd.println();
35 lcd.println();
36 lcd.println("DFRobot!!!");
37 lcd.println("TELEMATICS LCD SHIELD V1.0");
38 lcd.println();
39 lcd.setColor(RGB16_WHITE);
40 }
41
42 void loop(){
43 }

even i try too much in others codes the functions println (""), print("");only print one character from the sentence

i had open lcd libraries also and check it and i didn't found any print function that i can use

any suggestions ?
