HS3 ENERGY Errors - Object Reference not set to an instance of an Object

Ok

I've been playiong around HS3 for 8 months now I and I was getting ready to play with the energy database. I have 5 Aeon switch, 2 aeon energy monitor on my 2 electical panel.

First, I went in the configuration and activate the "Enable Energy Logging and Graphing" parameters and just to make sure I started clean, I clicked on the database clear button.

Then, I tried to go in the Energy option to see and play with the energy graph but as soon as I select the option in the HS3 menu I have the following message on a single line in my browser "error - Object Reference not set to an instance of an Object"

I tried once again to reset the databse but the message still appears.

On a side note, as soon as I activated the "Enable Energy Logging and Graphing" parameters, I started having the following errors in my log file:

Z-Wave Warning Failed to add energy data received for Switch Sous-sol aeon foyer - kW Hours to HomeSeer.

any clue on the issue ?

Thanks
