16X32 RGB Led matrix, multiple definition of matrix - c++

Question

I'm trying to make a project using the 16x32 RGB Led matrix, from the Adafruit store, but for some reason Visual Studio keeps telling me I've defined the matrix class multiple times.
This all started happening when I started making my own classes for my program (I'm still learning OOP). I have put define protection in the header file where I instantiate the matrix class, so that shouldn't be the problem
I've tried moving the class definition around. When I put it into the cpp file where I wanted to use it I stopped getting the multiple definition error, but then the matrix doesn't draw anything.
I've tried parsing a pointer to the matrix class to the class where I wanted to use the matrix but then I get this weird error where the matrix redraws the first thing it has to draw over and over again and it stops responding to serial input/doesn't give any serial output.
