Building Geometry but it does not show on end product

Greetings Unrealians ,

We are having some trouble when building our geometry on windows 10 . We hit the option on our 3rd person template with our fxb imported goods and build the light using the controls . Afterwards we go to package(on file option) , hit the windows 32 bits and select the route . After the installer ir ready it plays but doesn’t show all the resources we imported .The default floor and ladder are shown but not the rest of the imported assets .

Any advice welcomed.
