i have this code in my bib file:
@article{FDP_NZZ,
JOURNAL = "NZZ",
AUTHOR = "Erich Aschwanden",
TITLE = "Die FDP setzt im Wahlkampf auf Microtargeting",
MONTH = "Februar",
YEAR = "2019" ,
NOTE = ,
}
Why is the red underlined part in lowercase? I want it to be like the code (Die FDP setzt im Wahlkampf auf Microtargeting).

biblatexas your tagging suggests you may want to set addlangid = {nswissgerman},to your entry to show that it is written in (Swiss) German. In that casebiblatexwill not apply sentence case to its title. – moewe Oct 20 '22 at 18:49
