Tlc5940 - red apearing do be the dominant color

Specs: Windows 7
I'm currently working on a project where I am making an 8x8 LED matrix chess game. During this, I've encountered a problem with showing too many red and green colors on the same row.

The LED board is a 2388rgb-5 with common anode.

I use 2 daisy-chained tlc5940 to control the cathodes and a 74hc595 (here is the datesheet of 74hc595)

to control the anodes.

I have a lot of code so posting it all would be hard. I can do it if necessary.

I don't know if it has any correlation but the LED's are flickering when change is being made.
