RGBW Color out of range DPT 251.600

Hi all,

i work with OpenHab sind version 1.2 and i’m very happy with the product thank all for spend time on the product.

At the moment i have a problem with the color picker.

Follow configuration:
Thing / Channel:

  - id: Licht_Buero
    channelTypeUID: knx:color
    label: Licht Büro
    description: LED Streifen Büro
      increaseDecrease: 1/4/1
      position: 1/4/2+<1/4/6
      hsb: 251.600:1/4/10+<1/4/14
      switch: 1/4/0+<1/4/5


label: Licht Büro
type: Color
category: colorwheel
  - Buero
  - Licht_Gruppe
groupType: None
function: null
  - LightStripe

When i change the color (Tried in Ui, Item, Basic UI) i have mostly the error:

2023-10-01 21:19:17.558 [WARN ] [nx.internal.client.AbstractKNXClient] - Value '60,98,100' could not be sent to KNX bus using datapoint 'command DP 1/4/10 'knx:ip:0d0ca6957e', DPT 251.600, low priority': 251.600 RGBW color: RGBW component 255.0 out of range [0..100]: 255. Giving up now.
2023-10-01 21:19:17.558 [WARN ] [.internal.handler.DeviceThingHandler] - An error occurred while handling command '60,98,100' on channel 'knx:device:0d0ca6957e:9c45240554:Licht_Buero': 251.600 RGBW color: RGBW component 255.0 out of range [0..100]: 255

Some try works but most not correct, i didn’t see a message on KNX Bus when the error comes.

MDT DALI Control Pro64 SCN-DA641P.04S

OpenHab Version 4.0.3-1

Any idea what the problem?
Thank you for help me.

I think is a bug that the value convert from 0 -255 instead of 0-100 %
