Why can't I activate the purple terminal hexes on level 6?

So, I'm on level 6 and I have 2 purple energy hexes in the diamond shape: ------P------- -----P-P----- -------P------ There are two purple "terminal" hexes, and I have areas adjacent to them unlocked. For some reason, it's not letting me activate them with the color hexes. Is there something special I have to do for them?

There has to be a path to this terminals otherwise you cannot activate it. Or maybe color is wrong, sometimes I also wondered why I cannot activate something, but there are some variations on same color
