can't change font permanently in one note

[arpitdua]

I changed the settings to a different font Comic Sans and size 14. And it works fine if start a new paragraph and press enter. As soon as I copy some text from somewhere else, and then press enter, it changes back to the original font and size settings. I have tried various ways to copy and paste text to make sure that the font and size don't change but those ways do not work. What is the correct way to change the size and font?
