Cubase 15 keyeditor: how to switch midi note name for f TO JUST 'f' AND NOT e#

Cubase-15, Windows. In de Cubase 15 key editor the midi note name ‘f’ seems to have been canceled and replaced by ‘e#’ as default. How can I switch back to normal name? Working in C major here.

The names of the pitches in the Key Editor usually follow the Chord Track, where chords seem to superseed scales. Please look for a chord that would rather include an e# instead of an f.
