Removing distribute content from distribution point

[lucky41]

I can not removing a package / application distribute entry over the Configuration Manger Console or powershell command or WMI.
The entry is listed in the properties of the package or application tab “Content” on the package but the “Remove” option in the tab content doesn’t work.
The counter of the Content status not included this dp.
Monitoring\Overview\Distribution Status\Content Status\%package% not listed this distribution point (all other dp’s are ready)
The sql table “ContentDistributionNotification” has not entry from this dp package.

I hope you can help me and I can clear this issue on my sites (CAS with Primary sites).
