Custom IPS question

Somewhat new to EP but I've been tinkering with the custom IPS feature for website blocking. I'm just testing and have written two rules, one to block http://www.example.com and the second to block https://www.example.com. I know that it's working because http is being blocked but I cannot get the https to be blocked. Not exactly sure I'm doing wrong as the signatures are exactly the same except for "http" and "https" (I just copied and replaced)

Any help would be appreciated, thanks!
