These settings are kept in your browser with persistent cookies. If you browse in incognito mode, or have your browser configured to not retain cookies between sessions even if they're persistent, or manually clear cookies, then those settings will be lost. It is a long-time minor peeve of mine with the site because it is my policy to not keep cookies when I close any browser.
Why is lingq not remembering my settings anymore?
