Default [Q] Keyboard of Galaxy Note 2

Hi !

I went into Settings - Added Thai language in Samsung Keyboard in , " Input more languages " , but I cannot slide to change the languages from one to the other from the keyboard !
Though it does show me now two languages ie., English & Thai but does not change to Thai from English and neither do I see the two small arrows on the Enter button to change the language ! ( to slide left or right on the Enter button )
Can anyone please tell me if I have to do anything more or...? ( I am running 4.3 JB on Note 2 and have formatted my phone twice but still the same)

Thanks !
