pfSense RIPv2 configuration

I've got an updated 2.4.4 pfSense install that is inside my network. I've got several networks attached. The layout is as follows:

Internet -> Firewall/Router -> Network A L3 Switch -> pfSense -> Network B/C/D.

Internally we have been using RIP v2 successfully. pfSense is also intended to be a router for networks B/C. D is also routed on "Firewall/Router" and uses a different switch path to the pfSense install. Network A is connected to the WAN port on pfSense.

I've checked the box for RIP v2 and I'm seeing the pfSense show that it's the route via RIP broadcasts received by linux clients running RIPd in listen mode.

However, pfSense is also broadcasting it's the route for networks it doesn't route, such as A and D. I can't figure out why this is happening, but it causes network chaos. Is there a way to tell pfSense it's NOT the router for ALL networks it's connected to, and tell it which ones it IS the router for?
