Loadbalancing + traffic graph issue

[tripplex]

Have a look at the attachment, as you can see the traffic graphs are not reporting the correct figures while a load is on the wans. Its the same on the lan.

I restored from a pfsense 2.3.2 32bit build with different Nics to the current system i am utilizing currently. Will that cause any issues?

Would installing pfsense 2.4.0 64bit beta build resolve the traffic graph issue?

If not, What is the cause of this issue and how can i resolve it?

SPECS:
pfsense 2.3.2 p1 64bit
IBM think centre m57
hp nc364t quad port nic & intel pro 1000 t onboard nic.  FIVE NICS IN TOTAL.
Core 2 duo 2.0ghz
320gb sata hdd
1GB RAM

I upgraded to 2.3.3 with the new traffic graphs but the problem seem to remain. All Hope is gone now.
