Received two same LK4 parts. Can't plug the lightkey properly

I received two absolutely similar LK4 parts (Lego connectors for the Lightkey). But they should be mirror similar to fit. It’s it a packaging mistake?

Add photos if you can so we can see the parts and contact @yong

@Mac Please send us email at , we will send you the missing part as soon as possible.

I see one with the alignment hole on the left and the other with it on the right. It looks like you have a matched set. It was a little confusing during construction for me as well. Once I figured out the locking mechanism, it made sense.

Crazy I didn’t even notice that. Haha
