kalista ulti bug

i played a match as kalista with my friend (playing as teemo) bots match i used kalista item on teemo to bond with him but while doing that i activated the E somehow the system thinks i am bonded with teemo but i still got the item when i tryed to use my ulti i pulled teemo but he said he could't jump on the enemy we tried that almost 4 or 5 times but he can't jump teemo starts following kalista after the duration of the ulti ends even when he pressed B to back he kept automatically following me and spawned at the fountain after 8 seconds it also seems that the W passive doesn't work i got a screen shot and link to the match stats screenshot
