It is highly unlikely that you’ll get any help here with the screenshot you provided - it is not legible.  
That said, it looks like you might need to change the lacing settings of the node that assigns the material to longest.

cheers, will give it a go.

I will reupload the screenshot - this was the pic taken using dynamos built in option.

🙂  
That’s a quirk of the screenshot tool.  
If you zoom in closer and then take the screenshot the node titles and labels should be included.
