AssetBundle Load Problem

[over100mph]

Hi   
tk2d 2.5.4   my  unity version is  5.1.2

Create a sprite prefab made tk2d,
It made by assetbundle.
If you download and upload to the server test created assetbundle
Not this collection of information is set to 'tk2d sprite'.
When you create you have the information entered into prefab allow the collection to create a assetbundle
What ways are?

Are you using platform collections? You cant use platform collections directly with asset bundles, as the references are not directly linked.

I don't use platform collections.

I attach picture. Look at the green line.
After downloading a AssetBundle,
Sprite's collection is empty!!
How can this be applied to a collection set when creating a prefab?
