4K Video Downloader doesnt recognice 1440p60 on a YT Video:

I just downloaded the latest Verson but it seems a 2K download is still not possible.
Example: https://www.youtube.com/watch?v=omNCosKTqDM
It has 1440p60 Playback but 4K Video Downloader only shows Options for a Download up to 1080p60!
I downloaded Videos in 2K from YT with your Program in the Past, what has changed?!
