Z-plus problem in Zippo case

Hello, I bought the Z-Plus and it works fine, but when I put it in the zippo case the lid will not fit on it solid.

With the original Zippo insert, it stays on there good, you can't move it in any direction but upwards to open it.

With the Z-plus insert i can just wiggle the lid of the case to the left and right.


Anyone else has this problem or a solution?
