Default font size seems stuck

Hi all,

A couple days ago I increased the font size in a file, and then closed it out. The problem is now Atom starts up at that larger font size whenever I open a new file.

I’ve manually resized it multiple times using both the View>Decrease font size menu and Atom>Preferences>Editor>Font size, but no dice: every time I open a file, it starts at that enlarged size.

Has anyone else run into this issue or know how to solve it? Am I missing something? Thanks!
