Jayce melee skills are inescapable for le blanc

I just finished a Le Blanc vs Jayce game. Apparently his Q and E are locked onto me upon selection and I can not escape with W. For one instance, I use W from point A to B. He Q me at B, I W back right away to A, but then I got sent to B followed by a knock back from his E. What happened was when I was at point B, he Q E me, even though I already W back to point A, the E still activates and my body got sent back to point B. Throughout the game, I was not able to escape his Q with my W, whether it was first cast or second cast, once he makes that jump animation, his body would follow my W. I could probably be a Le Blanc bug instead of Jayce bug. Casting W too fast creates 2 bodies of Le Blanc, and target-locked skills going to the fake body will affect the real body? P.S. Totally threw off my game, couldnt do my 1 second combo around him.
