title: Google Analytics item category does not seem to be '/' delimited as promised
body: <p>After adding Item category and Item category 2 as row dimensions, this is what shows:</p>
  <p><a href="https://i.stack.imgur.com/jVY7I.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jVY7I.png" alt="&quot;question/competition&quot; under Item category is not delimited to separate columns" /></a></p>
  <p>This seems contradictory. How is this possible? Do they need to be capitalized?</p>
  <p>I send data in this format:
  <a href="https://i.stack.imgur.com/LC0yM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LC0yM.png" alt="enter image description here" /></a>
  Where getAnalytics() returns app.analytics() for a Firebase Application configured to Google Analytics with a Measurement ID.</p>
  <p>I'm also trying to make the purchase event work. I know that Analytics is receiving the 'value' property of '<a href="https://developers.google.com/gtagjs/reference/event#purchase" rel="nofollow noreferrer">purchase</a>' but it is not showing up in Conversions. Is there something that needs to be configured? Any feedback helps. Especially from those who have it working.</p>
