Desktop Central self-service portal displays applications already installed

Desktop Central self-service portal displays applications already installed

Hi,

we have just deployed Desktop Central in our company. We have created our packages and our "main" configuration to push packages to new computers. The software packages are configured to detect if the same software is already installed before proceeding with the installation.

We have enabled the option to automatically deploy non-commercial softwares to the self-service portal.

After running some tests, we see that the self-service portal offers the user to install software that is ALREADY present on the user's computer (instead of listing it as already installed like SCCM does). 

Is there an option i've missed?

Thanks
