Uploading .fxb cars into Unreal Engine 4

Good afternoon. I am trying to upload a car .fxb file that I found on a 3d model website. Unfortunately when I upload the car model into the engine is breaks it down into parts and pieces instead of loading the whole model. Has any one else experienced this? IS there a way to keep the original model whole when you upload it?

When you import the asset you need to look for a tick box that says something like - merge objects together - I cannot remember the exact name xD

Then hit Import after that
