Certain words in my dictionary (e.g. "th" for "the") are randomly disappearing. They will no longer work with WordFlow; I must type them manually. And then they are underlined in red. If I press the + to add it to the dictionary it acts like it added it, but it still is red/doesn't work. And I can try to add it again... and again... It simply won't add it. Does anyone know how to fix this?
