Issue with on_long button action and "service: light.turn_on" turning light off then on (using Philips HUE dimmer 929002398602 blueprint by EPMatt)

Configuration Blueprints

Hello to the community

I am running HomeAssistant on Ubuntu through a VM, with a Sonoff USB 3 Cordinator integrated into Zigbee2MQTT. I have the Philips HUE dimmer switch v2 device connected to MQTT through HomeAssistant.
I am using the Controller - Philips 929002398602 Hue Dimmer switch v2 blueprint found here:

Using the code below, all other buttons/actions work ok, except the on_long button.
Expected behaviour:
When the light is on and while holding it down, I want it to change the color temperature .
Actual behaviour:
First it turns off, then it turns on and proceeds to change the temperature. The off_long button (HUE button at bottom does not do that and works as expected).
Tried:
Accessing the action through just ‘device’ initially but couldnt access the temperature state changes. Toggle didnt work naturally.

It feels like it is detecting the short action on the button first. Is there a way around this? I have checked the forums but cannot find a similar issue but will keep looking.

I am attempting to use a timer from the following post but am struggling getting the code to work https://community.home-assistant.io/t/long-and-short-button-pressing-automation/466916/12. My idea is to have the action_short_press turn off only if it is pressed for less than 500milliseconds, and action_on_long press for temperature if more than (using part of the code in the link, more specifically:

condition:
  - condition: template
    value_template: >-
      {{ trigger.to_state.last_updated - trigger.from_state.last_updated  <
      as_timedelta("00:00:01") }}

Will keep working on this but if others have managed this, any guidance appreciated

Thanks
