Kalista passive and braum

Ok so kalista spammed her passive where she links herself to another champion (I was braum) mostly the support. After this, I couldn't do any spells with my keyboard with qwer and 1234567. This was really weird and near my loss I could do spells maybe because I tabbed out to right this post. So please fix this I lost a ranked game haha but I'm not worried about that because I know I can climb up.
