Controlling more than 8 leds in a single row

I am working on a project using an Arduino uno to basically create images on a 10X12 LED matrix. I can control the 10 rows fine however I can only control the first 8 LEDs in each row and then the final 4 just copy the first 4 LEDs. The columns are connected using 2 74HC595 shift register.

Circuit and code please.

There is something wrong with your code or your wiring or even both.

How do you expect us to know what you have done wrong without telling us what you have actually done?
