Yes, we know. It said so in the chapter and I've been pretty close to being sure about Layla not having the full set ever since the existance of the second (or rather the first, since chronologically it was built before the GMG Eclipse) Eclipse Gate was revealed.

But come to think of it: Did the GMG Eclipse Gate, since it didn't exist 400 years in the past from when the Dragons came, tap into the other Gate that Zeref, Anna and Layla used?

Or did it open a tunnel from just one side and went haywire because there was nothing and nobody on the past end to stabilize the time-tunnel?
