In English, the expression "one of those" is often used to mean "one of those kinds of things" or "one of those common situations."
It is especially useful at American academic conferences, seminars, and workshops when you want to softly describe an "unexpected situation," "something unavoidable," or a "common problem" during a discussion or presentation.
It has the nuance of "you know, one of those things," and is an expression that creates a tone that is both formal and natural.
