Fix for Access Control Blocking?

I had this issue with my RS300 after firmware upgrade that seems to have broken the Access Control page. One of the symptoms is devices being shown blocked, but not on the connected devices page. What used to work on the Access Control page was to select the device and click allow, this no longer works. I found a work around, disconnect the device from the network, wait until it shows up on the previously allowed list (ya a blocked device shows up on the previously allowed list). copy the  name and mac, and then remove and  re-add it to the previously allowed list. Re-connect the device to the network. At least for me the device that was shown as blocked now shows as allowed. Go figure.
