How do I change terminal font size in kali 2020.2

I've just installed the kali 2020.2 with kali-linux-2020.2-installer-amd64.iso in VMware 15.1.0. And I choose the default desktop environment "xfce". Everything looks good except when I open the terminal, the font size is too small that I almost can't see it. I clicked the "file" => "propertities" => "font" in terminal and changed the font size from 10 to 20. But after I clicked the "ok" button, nothing happened. And from the "properties" view, the font size is still 10. Could anyone tell me how to change the font size in the terminal in kali 2020.2? Thank you.
