CCS/TMS320F28069M: GPIO SET, CLEAR and TOGGLE not working to change the bit's value, but changing the DAT value directly does

Tool/software: Code Composer Studio

I am using the C2000 on the TSM320F28069M, if that's relevant. 

I'm trying to use the proper SET and CLEAR registers in my project, so I've gone ahead and configured them as GPIO pins with the following configuration function:

EALLOW;
    // their directions to outputs
    GpioDataRegs.GPADAT.all = 0x00000000;
    GpioDataRegs.GPBDAT.all = 0x00000000;

    // Define pin functions (as GPIO, I2C, PWM, etc.)
    GpioCtrlRegs.GPAMUX1.all = 0x00000000;  // GPIO0  - GPIO15
    GpioCtrlRegs.GPAMUX2.all = 0x05000000;  // GPIO16 - GPIO31
    GpioCtrlRegs.GPBMUX1.all = 0x00000005;  // GPIO32 - GPIO44
    GpioCtrlRegs.GPBMUX2.all = 0x00000000;  // GPIO50 - GPIO58
    GpioCtrlRegs.GPADIR.all  = 0x20030000;  // Direction of GPIO0  - GPIO31
    GpioCtrlRegs.GPBDIR.all  = 0x00000087;  // Direction of GPIO32 - GPIO44

    // Configure the ADC specific pins
    GpioCtrlRegs.AIOMUX1.all = 0xAAAAAAAA;  // Whether the ADC pins are in GPIO or ADC mode
    GpioCtrlRegs.AIODIR.all  = 0x0000FFFE;  // What direction each of the ADC pins are

    // Configure whether the pins are qualified by syncing to the System Clock, or otherwise
    GpioCtrlRegs.GPAQSEL1.all = 0x00000000; // GPIO0  - GPIO15
    GpioCtrlRegs.GPAQSEL2.all = 0x03000000; // GPIO16 - GPIO31
    GpioCtrlRegs.GPBQSEL1.all = 0x00000003; // GPIO32 - GPIO44
    GpioCtrlRegs.GPBQSEL2.all = 0x00000000; // GPIO45 - GPIO58

    // Configure the pull-up (removal of the pins connection) behavior of the pins
    GpioCtrlRegs.GPAPUD.all = 0x00000000;   // GPIO0  - GPIO31
    GpioCtrlRegs.GPBPUD.all = 0x00000084;   // GPIO32 - GPIO58
    EDIS;

And then i assigned them to Macros inside my header file. The relevant ones are as follows:

// Red LED for Debug
#define RED_LED_SET         GpioDataRegs.GPBSET.bit.GPIO34
#define RED_LED_CLR         GpioDataRegs.GPBCLEAR.bit.GPIO34
#define RED_LED             GpioDataRegs.GPBDAT.bit.GPIO34

// Step
#define STEP_PULSE_SET      GpioDataRegs.GPASET.bit.GPIO16
#define STEP_PULSE_CLR      GpioDataRegs.GPACLEAR.bit.GPIO16
#define STEP_PULSE          GpioDataRegs.GPADAT.bit.GPIO16

Yet, inside my code, whenever I call any of the SET or CLR commands (I even tried Toggle just to be sure) nothing happens. The code I used for that is as follows:

if (LEDDelay >= LED_PRD) {
		if (toggle) { RED_LED_SET; STEP_PULSE = 1; }
		else        { RED_LED_CLR; STEP_PULSE = 0; }
		toggle ^= 1;
		LEDDelay = 0;       // Reset the LED timer
	}
	else
	    LEDDelay += 1;      // Increment by 1 timer2 unit (1000 microseconds)

Using this code, the Red LED does nothing, never changing at all, while the pin (when hooked up to a scope) does change between on and off.

Essentially, I am able to toggle the data register directly, which I know is not-advised, yet I cannot use any of the SET or CLEAR commands. I even tried calling those directly (and not my Macros), inside that loop, to no change. I call InitSysCtrl(); before all of this main looping.
