How to correctly import assets into the IT Hardware Asset management template?

I'm setting up Assets for the first time, and attempting to use an object schema using the IT Hardware Asset Management Template, and the discovery tool to pull in assets from my network.

The discovery tool side of it is fine - I am able to scan the ranges I want and export via file or direct upload to JSM Cloud.  However... when the assets are imported into my schema, they all appear as generic hosts under Network Assets > Hosts, and not under the correct categories for Servers, Laptops, Mobiles etc.

Surely this product is not so limited that I can only correctly categorise assets in and out of the box template when I manually add them???
