Losing Promos, But I won?

Alright, so this is an odd one. I entered my promos as shown on the bottom Blitzcrank game in the screenshot below. http://gyazo.com/7dccfbb36b5426bbb4d0701570463602 I then proceeded to win one, lose one, and win one fully expecting to be in Gold 2 but rather being greeted by the "You have entered a promotional series" message. It appears as if my promo abruptly ended after I had lost the Leona game. I had not dodged any champion selects, and my promo was genuinely ended short. Does anyone have any idea whatsoever?
