I want to make own character 16x2 line LCD using CGRAM. There is no problem when i only write one character. But when I write two different characters on different address 80h and 81h(or etc.), there are two same character that have been written on LCD. Why is this happen ? This is my program :

start:
lcall INIT_LCD
...
mov a,#80h ; go to address 0
lcall WRCommand2LCD
MOV A,#00H ; Write character 0
LCALL WRChar2LCD
mov a,#40h ; write to CGRAM
lcall WRCommand2LCD
MOV A,#04H
LCALL WRChar2LCD ; write row 0
MOV A,#00H
LCALL WRChar2LCD ; write row 1
MOV A,#04H
LCALL WRChar2LCD ; write row 2
MOV A,#04H
LCALL WRChar2LCD ; write row 3
MOV A,#08H
LCALL WRChar2LCD ; write row 4
MOV A,#11h
LCALL WRChar2LCD ; write row 5
MOV A,#11H
LCALL WRChar2LCD ; write row 6
MOV A,#0eH
LCALL WRChar2LCD ; write row 7

mov a,#81h ; go to address 1
lcall WRCommand2LCD
MOV A,#00H ; write character 1
LCALL WRChar2LCD
mov a,#40h ; write CGRAM
lcall WRCommand2LCD
MOV A,#04H
LCALL WRChar2LCD ; write row 0
MOV A,#4H
LCALL WRChar2LCD ; write row 1
MOV A,#4H
LCALL WRChar2LCD ; write row 2
MOV A,#4H
LCALL WRChar2LCD ; write row 3
MOV A,#4H
LCALL WRChar2LCD ; write row 4
MOV A,#4H
LCALL WRChar2LCD ; write row 5
MOV A,#4H
LCALL WRChar2LCD ; write row 6
MOV A,#00H
LCALL WRChar2LCD ; write row 7

Which part that i have to change in my program ?
I read article Myke's Website (www.rentrom.com) how to make graphic characters, but he only write different characters on the same address (80h). And if I Write a command to LCD my command is not working. Like 14h command (cursor shift rigth). the cursor jump to address C9h and write same character like on 80h address
