Help I mistakenly delete the loop network and loop predefined rules

Is my security being compromised by deleted this looping network? COMODO doesnt set the loop network automatically again once it’s deleted.

And how do I bring back the loop’s predefined firewall policies for all category?(Web, email, ftp, etc). How to set it?

Thanks

I already set a looping network manually I call it Loop back IP In [127.0.0.1 / 255.0.0.0]

Is this correct?
