Help in adding references

Development Programming & Scripting Blueprint

Im currently stuck on a option where i need to add a reference to my sliding door im trying to create. Im watching this (- YouTube) tutorial and when i add a reference it adds 3 points instead of one. i have 2 door handles and the glass panel in one group but im not sure what im doing wrong. here is a screen shot of my current blueprint.

I’m not sure if adding grouped objects would work for this, i suggest you create them in a blueprint, this will allow your 3 objects to be classed as one.
Create a new blueprint actor, under components add 3 static meshes and change them to your 3 components.
