Memory breakpoints not triggering

[Altimor]

I got a compiled x64 debugfast build from http://forums.dolphin-emu.org/Thread-break-points-memory-editor-and-debug-mode and memory breakpoints don't seem to be working. I've tried clicking next to the address in the memory view and manually setting the address range from the breakpoints tab. Nothing shows up in the log and the breakpoint doesn't trigger even though I can see the value being written to in the memory tab and the game obviously reads it when I change it.
