Ezreal Q Bug on Monsters [Gameplay]

So I was playing a game as Ezreal and noticed that when I used my q on monsters i was not getting the cooldown buff that reduces cooldown on all abilities. To be specific i did this at a wolf camp and all my abilities had their cooldowns reduced by 1.5 seconds with the exception of my Q. This obviously made jungle times take longer.

To recreate: This was in a ranked game if thats any relevance I had iceborne gauntlet and was using the frosted ezreal skin. also as mentioned above this only applied when I attacked monsters (wolves)
