KB8000822 Pending Install after removal

unfortunately we fell victim to Microsoft's KB5000808, 802 and 822 updates.. the latter being on our print server which was falling over everytime someone printed to a Kyocera printer.

I've managed to uninstall the update with the WUSA /UNINSTALL /KB:5000822 command and I've set it for removal via our WSUS server but irritatingly it says it is pending installation when I check in the Update settings on the server.

Is there a way of stopping this from being available to install? I've cleared the software distribution folder but nothing seems to get rid of it.

thanks in advance,

Paul.
