TM4C1294 - Unable to use TimerXA and TimerXB together for TimerX

Hello,

I'm using the TivaTM4C1294.

I'm using Timer5, which is split into two 16 bit timers - TimerA and TimerB. The clock to the timer5 module is the PIOSC.
Both the timers are set to interrupt at rising and falling edges and are configured in Edge-count mode.

If I use either Timer5A or Timer5B as standalone timers, they work well, interrupting as usual. However, if I enable both of them, only Timer5B triggers.

Added code below:

Timer5A config

    SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER5);
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOM);

    GPIOPinTypeTimer(GPIO_PORTM_BASE, GPIO_PIN_6);
    GPIOPinConfigure(GPIO_PM6_T5CCP0);

    GPIOPadConfigSet(GPIO_PORTM_BASE, GPIO_PIN_6,
                         GPIO_STRENGTH_2MA, GPIO_PIN_TYPE_STD_WPU);

    /* Clock the timer using the PIOSC - Precision Internal Oscillator
     * @16MHz.
     */
    TimerClockSourceSet(TIMER5_BASE, TIMER_CLOCK_PIOSC);

    /* Configure the timer in half-width edge time capture that counts up. */
    TimerConfigure(TIMER5_BASE,    (TIMER_CFG_SPLIT_PAIR         \
                                  | TIMER_CFG_A_CAP_TIME_UP));

    TimerControlEvent(  TIMER5_BASE,                             \
                        TIMER_A,                                 \
                        TIMER_EVENT_POS_EDGE);

    IntEnable(INT_TIMER5A);
    TimerIntEnable(TIMER5_BASE, TIMER_CAPA_EVENT);

Timer5B config

    SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER5);
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOM);

    GPIOPinTypeTimer(GPIO_PORTM_BASE, GPIO_PIN_7);
    GPIOPinConfigure(GPIO_PM7_T5CCP1);

    GPIOPadConfigSet(GPIO_PORTM_BASE, GPIO_PIN_7,
                         GPIO_STRENGTH_2MA, GPIO_PIN_TYPE_STD_WPU);

    /* Clock the timer using the PIOSC - Precision Internal Oscillator
     * @16MHz.
     */
    TimerClockSourceSet(TIMER5_BASE, TIMER_CLOCK_PIOSC);

    /* Configure the timer in half-width edge time capture that counts up. */
    TimerConfigure(TIMER5_BASE,    (TIMER_CFG_SPLIT_PAIR         \
                                  | TIMER_CFG_B_CAP_TIME_UP));

    TimerControlEvent(  TIMER5_BASE,                             \
                        TIMER_B,                                 \
                        TIMER_EVENT_POS_EDGE);

    IntEnable(INT_TIMER5B);
    TimerIntEnable(TIMER5_BASE, TIMER_CAPB_EVENT);

    TimerEnable(TIMER5_BASE, TIMER_A);
    TimerEnable(TIMER5_BASE, TIMER_B);
