Why does font keep defaulting to Avenir Next?

I use the Chalkduster font for all my notes. At least twice a month, sometimes weekly, I'll open my notebook to find everything has defaulted to Avenir Next. I go back into settings, I change it back to Chalkduster, and guaranteed, I'll be doing it again in a week or two. What is going on, and how can I make it stop?

PS:  a default font color would rock my world.
