[Q] Q about sony keyboard topic

I remember nice function from 4.1.2 where I could type word using swiping feature, keyboard would delete that word if i pressed x or delete button or whatever.
In 4.3 when i type word using swiping, pressing x only deletes 1 last character of that word. I tried 4.1.2 keyboard but that didn't seem to fix it. Any suggestions?
