LowActive() causes weird Fade behaviour

[RossAWaddell]

I need to connect the -ve pin of LEDs to the Arduino as I'm using a ULN2803A transistor to power 10 5mm LEDs. As this is the opposite of the usual single LED connection I'm using the LowActive() method to invert the fade, but it does a weird blip at the beginning which I don't see when connecting the +ve LED lead to the Arduino pin.

Any idea what's happening here? Ideally I'd like a smooth fade from off to the max brightness value.

JLed(AMBER_LED_PIN).FadeOn(AMBER_LED_FADE_UP_TIME).MaxBrightness(MAX_BRIGHT_AMBER_LEDS).DelayAfter(250),

      .MinBrightness(MIN_BRIGHT_AMBER_LEDS).DelayAfter(250).Forever()
};

JLedSequence amberLEDseq(JLedSequence::eMode::SEQUENCE, leds);

void loop() {
    amberLEDseq.Update();
