title: FIX market data request issue - Incorrect NumInGroup count for repeating group
body: <p>Im trying to get a market data by FIX protocol. This is what Im sending as a request:</p>
  
  <pre><code>8=FIX.4.4|9=120|35=V|34=2|49=icmarkets.3540639|52=20190917-05:55:39.114|56=CSERVER|262=2|263=1|264=0|265=0|269=0|146=1|55=EUR/USD|267=2|10=173
  </code></pre>
  
  <p>and this is the response received:</p>
  
  <pre><code>8=FIX.4.4|9=163|35=3|34=2|49=CSERVER|50=TRADE|52=20190917-05:55:39.142|56=icmarkets.3540639|45=2|58=Incorrect NumInGroup count for repeating group, field=267|371=267|372=V|373=16|10=216
  </code></pre>
  
  <p>So there is obviously an error <strong><em>Incorrect NumInGroup count for repeating group, field=267</em></strong>
  but I have no idea how to fix this. Any tips?</p>
  
  <p>Thanks! </p>
