33522A PWM Modulation Behavior

I've tried to simulate a pulsing pwm-driven LED with these parameters:

Waveform: Pulse
Frequency: 200Hz
High Level: 3V
Low Level: 0V
Duty Cycle: 50%
Edge Time: 9ns (both)

Modulation Type: PWM
Source: Internal
Duty Cycle Deviation: 40%
Shape: Triangle
PWM Frequency: 1Hz

While modulating the pulse wave, i noticed dropouts. The pulse wave is missing a pulse. This happens periodically with the modulation frequency (1Hz).

Device: 33522A
