When I'm using the bibstyle "plainnat" the sort&compress option is not effective. Whereas when I use another bibstyle (els-article) -from the publisher Elsevier- it works perfectly.
Can you explain me why

My bibliography is done through Jabref.
I use \citep{Aut1,Aut2} in the document
Here is the header of my document:
