Urgent help pls! 64x64 matrix won’t work properly

Hello, I got 4 32x32 RGB matrices from the adafruit store in addition to RGB bonnet. I assembled the matrices in U shape to make 64x64 matrix. I used the raspberry pi 4 for this project. I read that in order to let the bonnet work with the 64x64 matrix I need to solder E pin with 8 pin on the bonnet so I did so. The problem is whenever I tried to display a scrolling text or a normal picture on the matrix, whatever I display it split up like the picture shows

I should mention that I put - - led-pixel-mapping = U-mapper but it still split up. Any help regards the coding or hardware is appreciated and thanks!
