No worries.
What it does is for every static lease it creates a pair of rules.
Block any packet whose MAC is X and IP isn't Y
Block any packet whose MAC isn't X and IP is Y
Together all of those rules make sure that all devices use the IPs you assigned. If your devices are all under your control and not hopping IPs, it's not needed.
I'll try and look into why these rules slow down the firewall so much. I don't know if it's just the number of rules or the order they're looked at but that's a BIG impact.
