Puzzle glitch or just stuck?

I qam on the puzzle with x's and o's im stuck im sure i did it right but the doors wont open any advice?

On the one where you need to match 3 (http://imgur.com/aFDO9gF) the rightmost design should be the two hemicircles, the "<" sign, and the "\" sign. You should NOT use the ">" sign. Hope that helps.
