Job overdue stats increased a lot

Navdeep Singh  
I just saw my freelance stats where suddenly overdue numbers has increased from 3 to 8. This is shocking as I clearly remember 3 overdue jobs ( even these were because of client delay but it is okay ) but no more than that exists although I have a job where the client suddenly disappeared ( almost 2 months now ) and is not active anymore. Could this job only be contributing to my overdue numbers ( as the algorithm may calculate it like that ) which also brings me to my second question, how can this job be finished? Can a moderator forward it to the concerned people or arbitration is the only way ( which I have been avoiding as it shows in our own stats ). I could have posted this job link but I am not sure if that is allowed
