Good catch awesomejannick -- I believe the square and circle were swapped by mistake and should yield a unique solution when you trade their contents. I'll fix this as soon as I'm able.

This one is impossible to solve... The result of the second grid will have different numbers in the solid square and the solid down-pointing triangle (since their in the same column), but the third grid is only solvable if the corresponding dashed shapes have the same number (either both 2 or both 4)
