Block alert options in firewall

Hello,

When the firewall popped up an alert up until a few weeks ago, it gave me the option to “Block”, “Terminate” or “Block, Terminate and Reverse.” Now when an alert pops up, it gives me only two options, Block or Terminate, but not the third option, as of ~Nov. 5, 2015. Has Comodo changed something, is there more than one type of alert, or have my firewall options been hacked?

Thanks for any help.
