Remove old package still show up in Content->Packages

Hello Team,

On foreman-3.3.1 with katello-4.5.1, I uploaded a custom package with a wrong filename “package_name (1).rpm” but the real name is “package_name.rpm” in the packages list I see “package_name”… (my puppet client try to install it, but it cannot find the package… because the filename is not good)

I had remove it from my custom content. But it still displayed in “Content/Packages”. How can I completely remove it ?
