lcd.print slows down port manipulation

All my inputs (PINL) are fine over serial monitor but now that iam using an LCD screen ..i have only got it to print my if statements 3 times..is lcd.print slowing the code down ..any ideas?

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);
void setup() {

  DDRL = 0b00000000;  // Sets ports to read
  lcd.init(); // initialize the lcd
  
  lcd.backlight();
  lcd.print("DRERSCSNCLCHSDCR"); // abbreviations for registers DR-ER-SC-SN-CL-CH-SD-CR 
}

void loop() {

  // put your main code here, to run repeatedly:
  lcd.setCursor(0,1);
  if (PINL == 0b01000010) //if PINL returns the right value print "OA" under DR thats always printed to the lcd
    lcd.print("OA");
  lcd.setCursor(2,1);
  if (PINL == 0b01001010) //if PINL returns the right value print "1A" under ER thats always printed to the lcd
    lcd.print("1A");
  lcd.setCursor(4,1);
  if (PINL == 0b01010010) //if PINL returns the right value print "2A" under SC thats always printed to the lcd
    lcd.print("2A");
  lcd.setCursor(6,1);
  if (PINL == 0b01011010) //if PINL returns the right value print "3A" under SN thats always printed to the lcd
    lcd.print("3A");
    lcd.setCursor(8,1);
  if (PINL == 0b01100010) //if PINL returns the right value print "4A" under CL thats always printed to the lcd
    lcd.print("4A");
    lcd.setCursor(10,1);
  if (PINL == 0b01101010) //if PINL returns the right value print "5A" under CH thats always printed to the lcd
    lcd.print("5A");
    lcd.setCursor(12,1);
  if (PINL == 0b01110010) //if PINL returns the right value print "6A" under SD thats always printed to the lcd
    lcd.write("6A");
    lcd.setCursor(14,1);
  if (PINL == 0b01111010) //if PINL returns the right value print "7A" under CR thats always printed to the lcd
    lcd.print("7A");
}

is lcd.print slowing the code down

It very well may be, because you're doing things in the most inefficient way I could possibly imagine. On EVERY pass through loop you're moving the cursor 8 TIMES in preparation to print when you're only going to ever actually print one time AT MOST. Instead, determine which (if any) of the special values PINL is. Then, move the cursor to that one spot and print. Then, be done with it.

Also, I assume you realize that once one of your special 2-character codes is printed in its spot, it will remain there permanently because you don't have any code to remove it. Is that your intention?

I did only what to move the cursor after the if (PINL==) but if I try..
If (PINL==Ob00000000)
setCursor(1,0);
lcd.print("OA") ; ...it does not work..yes I want the 2 characters to stay after they are printed..

Because you don't have the required Curly Braces
