Default account option is greyed out in Notes app
I'm running the latest version of yosemite. I have 3 different accounts - an iCloud - a gmail - and an exchange account. In previous version of OS X - if I recall correctly - I could select the "default account" in the notes app. However, that option is greyed out now. This is a problem - because without being able to set the default account - it creates notes under the top listed account in the app - or whichever account is highlighted.
Any idea how to rebuild / fix this issue? I've tried deleting the file under user/library/container - I've tried deleting and setting up the accounts - I can''t seem to get this option to appear - it is just "greyed" out.
Thoughts on how to fix?
