Comodo Firewall blocking network access to Windows services and OS?

Over the past week I've had Comodo Firewall blocking network access to a couple of Windows services and I can't understand why. On Monday it went and blocked three svchost.exe inbound connections, on Wednesday it blocked a MSASCui.exe inbound request (Windows Defender. It keeps turning itself on even though I disabled multiple times a week) and within the last hour I've had it block a outbound request from "Windows Operating System". I've unblocked all of them.

Any reason for this? System...
