Team builder icon not being credited

Prior to the 4.20 patch, I had 4 out of 5 games toward the Fighter icon. Since installing the patch, I've played two games as Jax in teambuilder (same champion + role, jungle/fighter, I played for my first four games), and both times I was not given any kind of notice related to the icon upon leaving the post-game lobby. I have since earned 2 tank and 1 mage progress towards those respective icons, but my Fighter progress seems to be stuck at 4. Any suggestions?
