Export "Stock Availability" results

Hello everyone,

May I ask you how I could export the results of “Stock Management”>“Stock Availability”?
Both the button “Export” and “Export Full” give me the list WITHOUT that columns…

Another strange thing is that if I click on one of that columns,i receve an error message "No such field ‘$stockMin’ in object ‘com.axelor.apps.base.db.Product’ ", instead of filtering…
there are any way to solve/get the same result?

Thanks
Gabriele
