title: MySQL duplicate FK values in myPhpAdmin dropdown list
body: <p>I've built my first ever simple MySQL DB with the myPhpAdmin interface.</p>
  <p>1st users table: id (PK), email, fname, lname, isConsultant [bool]...</p>
  <p>2nd consultants table: id (PK), title, bio...</p>
  <p>3rd table linking both (some users are consultants, some are not): id (PK), user_id (FK), consultant_id (FK).</p>
  <p>I have Primary Key and Foreign Key well assigned (I've followed quite a few video tutorials).</p>
  <p>Now when I test and try to insert values into my 3rd table, I see &quot;duplicate&quot; options offered to me by the myPhpAdmin interface:</p>

  <p>What did I do wrong? Please if you could use simple wordings since I'm new to this!?</p>
