Error when using Energy Loss API in EDEM

Hello,

I am working on fluidized particules bed.
I am trying to record energy losses due to collisions on a surface and I would like to use the API with customs modification of the energy loss property.

When I select the API as a plugin model and I run my model, I get the following error when I want to plot the energy loss for every collision in the analyst :

 "WARNING : User Defined Properties : Too much data in file for property: Previous Forces Discarding excess."

I get the same message for all variables used in the API file. (Previous Velocity, Previous Torque, Energy Loss...)

I don't understand how to overcome this error and to be able to read those data in EDEM ( Analyst -> normal energy loss) or with edem py.

Sincerly,
Max.
