CLM filter for patches with patch advisory name do not work

[AxHuGH]

Dear all,

We are using the LCM facility to stage package through systems.
We have a base filter for denying packages more recent than a specific date.
We have now created a filter for a patch with the advisory name and used the Allow rule.
However, this patch is never visible on the client systems.

Does the Deny rule contradict the Allow rule here?
Or is there a conflict between the Deny rule for packages with a certain date and the Allow rule for patches?

Regards
