title: Import popup not displaying
body: <p>In my IntelliJ, auto import pop-up is not displaying although "show import pop-up" is ticked in the settings so I always have to manually type import java.util..... at the top. </p>
  
  <p>I found some similar questions and tried out their solutions, but none of them worked.</p>
  
  <p>I'm new to Java and started using IntelliJ just a week ago, but if I remember correctly the pop-up was displayed at first. 
  I didn't update any settings and have no clue how I can make it back.</p>
  
  <p>Also, unlike many screenshots of other people's intelliJ, the color of code in my intelliJ are all white except for some keywords which are orange and string which is green.</p>
  
  <p>Not sure if it has something to do with this issue tho.</p>
  
  <p>Could anyone help me find out what could be a problem?</p>
