The Title buttons problem

Recently I did some changes to my latte, and since from there my title buttons i.e, close, maximize and minimize buttons are appearing on a separate window border but previously it was to be on the latte itself . Any quick solutions would be must appreciated.

BTW, HERE is a pic :

You remember wrong. This is the normal appearance (buttons on windows, when they are not maximized).

Latte buttons have several settings for their behavior. Change them to your preference.
