Garageband Component file problem

I put my component file in te library. First time the Garageband can recognised it. Then I delete the file and put a new one the same component file. Garageband can not recognised it anymore.
How can fix this problem. I already try delete the cache and it not working. PLS help!!!

I guess there must be some difference between the new and old file?

I put a same file in to the library plugin
