In conflict with Sumo discount

I installed Sumo discount yesterday and it seems to conflict with field factory.
When I apply a discount of 15%, the discounted price appears correctly on the product page and on the catalog.
But when the product is put in the basket, another discount of 15% or more is added on the product…
For example, for an item at € 107, the price of the catalog and the product that will be displayed will be € 90.95 but when the product is added to the basket, the price becomes € 77.31. The reduction is counted in double …

If I deactivate field factory, the discount works normally but unfortunately I can not do without any of these pluggins for my company.

Could you tell me how to fix this problem, or if there is an incompatibility between these pluggins can you resolve it ?

Thank you in advance,

Regards.
