When P10 sends data to the left of the screen, the fixed texts on the right play

When P10 sends data to the left of the screen, the fixed texts on the right play. This may be the reason.

#include <DMD2.h>
#include <Fonts/Arial_Black_16.h>

SoftDMD dmd(3,1);
DMD_TextBox box(dmd, -1, 0, 96, 16); 

void setup() {
  dmd.setBrightness(100); // Set brightness 0 - 255 
  dmd.selectFont(Arial_Black_16); // Font used
  dmd.begin();     // Start DMD 
  dmd.clearScreen();
  
 Serial1.begin(9600); }
  
void loop() {
 
if (Serial1.available() >0) {
   
int inByte = Serial1.read();
box.print((char)inByte);  }}

Does anyone have any ideas as to why? When you send data to the left, the fixed data on the right plays strangely.

There is nothing in your code that able to print fixed text in the right.
Please show a full code

Okay, please record a video starting from the start of the program, when there is nothing on the matrix yet. And until the moment when two-digit numbers appear on the left
