How to get rid of the "Calibri" font?

[Antikapitalista]

I cannot switch the default font to the downloaded and installed Aptos font. No matter what I do, which Normal.prvx template I edit, the default font "Calibri" always comes up at the start of Presentations 2024. How to get rid of the default font?
It would be helpful if Presentations had the same option for setting the default as TextMaker has.
Even if I hide the font in the font visibility settings, it always comes up as the default one, although it is subsequently not displayed in the font list.
