title: DataGrip diagram not showing table relationships
body: <p>I have been having this odd issue where my DataGrip diagram generations do not showcase the relationships between tables (in other words, the relationship arrows do not appear). </p>

  <p>Here is an image of what I am talking about.</p>
  
  <p>I have been making this DataGrip diagram as such: <strong>Right click on my schema --> Diagrams --> Show Visualization</strong>. The above image is the result every time.</p>
  
  <p>How can I fix this to show the arrows? <strong>And before you ask, I have foreign keys in my schema tables that reference other columns in other tables.</strong></p>
