Keyboard feature in 4.3. Help! topic

I've been using Sony keyboard for the past year and it was a good experience so far. Not anymore under 4.3. I'm using swype and 3 languages inputs. Before 4.3 update i was able to manually change my input language and when I wanted to input, with swype, a word and got it wrong I could just press delete once and the whole word would dissappear. Now detele works with letter by letter. And since I have 3 language dictionaries forced altogether my wrong word percentage has increased drastically.
Using swype has become really frustrating for me.
I've tried to change these features in settings but I couldn't find them.
If anybody has any suggestions on how to setup the keyboard i'd really appreciated. Thanks
