Fan/Light notif LED - Chase doesn't work?

I’m running Home Assistant and calling services like so:

service: zwave_js.bulk_set_partial_config_parameters
data:
  parameter: "24"
  value: 50989649
target:
  entity_id: light.red_series_fan_light_switch

I’m referencing the Nathan tool and it seems to work for everything (color, brightness, etc) except the “Chase” effect. It works for solid, slow and fast blink, and pulse. But not chase. Instead, it just slow blinks. Any ideas?

It works, it’s just that the Nathan tool seems to be out of date or wrong regarding the chase effect. If I do it manually, like this, it works fine:

service: zwave_js.bulk_set_partial_config_parameters
data:
  parameter: 24
  value:
    0x7f000000: "Chase"
    0xff0000: 10
    0xff00: 2
    0xff: "Red"
target:
  entity_id: light.fan_light

@nathanfiscus FYI.
