Sat 6 Content Views showing errata that should not be shown

I have one environment named Library and two content views in there, dev and prd.

I have set the dev content view to include everything, no filter. The prd content view is set up to include security, enhancements and bug fixes. I have the start date of this filter left blank and an end date on Dec 1st 2016. I have assigned a client to this view but under the Errata tab of the system I see some errata with a date issued after 12/1/16.

I have added another client to this prd view and I also see errata available with a date after 12/1/16.

Any ideas?
