The term "life cycle" shouldn't be hyphenated. This should be fixed in the main menu and anywhere else it appears on the site.
More info: Hyphenation is used when two words work together as an adjective, but not when they're used as a noun. The life cycle of a frog is a thing. (Used as a noun, so no hyphen.) Life-cycle analysis is a kind of analysis, and a life-cycle process is a kind of process. (Used as an adjective, so hyphenate.) In this case, we're using it as a noun, so there should be no hyphen.
