Kalista is rly weird now in 5.1 patch, I just feel it .. duno but every second or third jump does not work for me! i am jumping and she just stop again and again ! ist that bug or what ? i know how to play i buy her when she comes out ... ??
As a Kalista main, heres what I've noticed:
Kalista is still capable of jumping with every attack, but:
Either the window to enter a movement command has been drastically shortened, or
Clicking outside of the movement range will not register.
I'm about 90% sure it is the first, because that would fit with the change made to her passive in 5.1. I'm thinking the time period in which one can change the target selection doesn't count for the window in which Kalista can proc her passive. At the beginning of the game, her attack speed is low enough that the difference is negligible, however if her attack speed increases even a little bit, it becomes difficult if not impossible to actually use her passive. This makes her a lot less viable than other adcs because she still can't cancel a basic attack and she has basically no base movement speed. In a way, this bug punishes Kalista for building the one stat she is supposed to have.
I've noticed it's a lot harder to get Kalista to jump whenever the cursor is outside her movement range, so that's another possibility, but I'm thinking that it's more likely that the window to enter a movement command has shrunk to an unmanageable level. In addition, while the window to enter the movement command has shrunk, the blue indicator at Kalista's feet still remains for the full amount of time, so even if you have the reflexes to keep up with the extremely small window, the game can fool you into thinking you have more time than you actually do, or that you can enter a movement command before you actually can.
All in all, Kalista is completely broken right now, I would recommend sending in a bug report and not playing her for now.
same thing for me really annoying
happens tome too, ive mained her since shes come out its off now.
yah same, i just played her today and noticed her passive barely working and ends up getting me killed coz i cant kite effectively
YES! YES! YES!!!!!!!!! God I'm so mad about this too. She just can't jump. I tried it too.... I feel you...
was playing kalista last game and couldnt move passive worked maybe 1/5 times i just made a discussion saying the same thing and its really really annoying I could have dominated last game but I just couldnt dash away :l Really sad pls riot
They need to fix this asap.. I'm also a kalista main and I will not be playing her until its fixed.
Care bear said everything I wanted to say and more. Rito, pls. 
Also this happened before patch 5.1, but spamming attack move will make Kalista's jump animation glitch out, and it's REALLY annoying
I just played two games with her, and I have the same problem. I played her quite a bit before this patch and did not have this problem. Even if I shorten the distance I click with my movements, it doesn't always proc. Really frustrating.
the passive fubared right now. my favorite champ and she is borderline unplayable
Just played my first game of day and couldn't orb walk at all. The irony. The passive meant to make you orb walk like a god keeps you from moving at all. Luckily I still went 20/5 and won :P
im having the same problem bro
