sierra storage and garageband

I have Mac OS 10.12. "About This Mac" tells me that GarageBand is using 8.11 GB of storage. Then I check"Manage Storage" and I find out that it is "Garageband instruments and lessons" that are using up 8.11 BG. However I had already moved the Garageband app off of my hard drive. I check for large Garageband files in the library and none of the GarageBand files are even 1 GB. Does anyone know why my computer would be allotting 8 GB for this non-existent app??
