Remove a duplicate JDK in JDK choice list in IntelliJ IDEA

While choosing the right JDK for the project I imported the same JDK twice which resulted in the same JDK appearing twice in the selection list. This is ugly and can cause confusion in the future. How can I remove the duplicate? There must be a configuration somewhere which controls it.
