realestate.com.au: PLEASE WORK!

I don't know about you, but I love the 'Map' feature on re.com.au, which has now been around for quite some time. What I ABSOLUTELY HATE about it, is when I choose to limit to 4 bedrooms, that's right, 4, and i get a gazillion 3 bedroom properties. That's right, 3. So what gives?

Please fix this re.com.au, I love the new functionality, but something this simple needs to be addressed.
