Byobu F1 help closes current window

Somehow when I press F1 Byobu opens its help page in the current window. After closing the help page the window is closed. I am running Arch Linux. While working with vim I often hit F1 by accident instead of ESC and my vim session is closed. This is so frustrating.. On my server(Ubuntu 18.04) the byobu help page is opened in a new window when I press F1. According to the help page the F1 key is * Used by X11 *. How can sort this out/change this?
