SetColorTemperature does not accept numerical values even if they are inside the Supported Range [Alexa]

[Sab44]

Describe the bug
When setting color temperature via Alexa, I can say temperatures like "white", "warm" etc. without any issues. But trying to set a numerical value always yields the response "the value is outside of the supported range of device xy" (paraphrasing, as I have german as language).
My range is set to 2200 - 7000. It does not matter if I say "set xy to 4000 (kelvin|degrees|other variations)".

Side note: if I say the same command with any value from roughly 0 - 1000, Alexa will accept the command, but instead execute a SetBrightness with values between 0 - 100 depending on the number I said (so 200 will be mapped to 100, but 810 will be mapped to 10).

To Reproduce
Add a light device with "Color Temperature" interface.
I have additionally configured "Brightness", "Color" and "Power". See screenshot below.
Call the "Alexa, set Color Temperature of xy to 4000 degrees" command.

Expected behavior
According to the documentation

Set color temperature command output, used when specifying values either by name, or numerical value in Kelvin:

msg.payload will a numerical value, representing colour temperature in Kelvin

Log Output
Message does not arrive in Node-RED.

Environment (please complete the following information):

• Node-RED node version: 0.4.68
