App Store (CMApplicationCatalog) storing PC linked information

Hello All,

In testing a newly packaged application I installed it from our 'Enterprise App Store' and then uninstalled it. Problem being that now it appears in my 'Software Center' as an available App and constantly prompts me that there are available Apps that I can install. I have deleted the PC object from SCCM (not at a database level as I don't have that access) and have reinstalled a fresh OS; however it still prompts me.

Does anyone know where this PC to App link is stored so I can get it deleted?

Thanks
