node module not working

My node page is not updating and is showing  NaN W or NaN V. Only the first two inputs have values but I think they are always showing 5140W even after reinstalling. 

I have emontxv3 with CT1, 2 and 3 attached and the voltage transformer. Originally I was using the emontxv3_continuous_kWhtotals_noeeprom sketch but couldn't get the nodes page to work so reinstalled emoncms v8.08 with blank database on the rpi and loaded the emontxv3_rfm12B_discretesampling sketch to the emontx.  Despite this the nodes page still doesn't work.

If I click again on the  http://192.168.1.103/emoncms/node/set.json?nodeid=10&data=20,20,20,20  link on the node api help page I get undefined offset errors as screenshot below. There are also extra inputs on the inputs page that don't exist.

Does anybody have any ideas what I'm doing wrong.
