Kalista's Martial Poise a little unresponsive

So I've been playing Kalista, ever since she came out, basically. She is my main adc, and I really don't ever adc unless I'm able to pick her. I remember with her Martial Poise passive, it did take a little getting used to, but after so many games, I was able to jump circles around people no problem. However, I've played her a few times recently, and her passive is a bit unresponsive. I'll right click just fine, but she won't jump, OR if she does jump, she doesn't continue to autoattack like she used to. Instead, she'll jump and run to where I clicked, and not attack. I don't know why this is happening. I've unplugged my mouse, and replugged it in thinking it was my mouse, but it's not. It's almost as if it's registering as a double right click, making her jump then run to the clicked location. Before, you could right click anywhere on the screen, without it having to be right next to her, and she would just jump and continue attacking, unless you clicked multiple times for her to just run. I don't know if this is a bug, but it's really killing the fun I get with playing as Kalista. I would love to get a response from a Rioter in regards to this. It's happened ever since the new elements to the game have been implemented.
