Ecommerce tracking conversion problem

Hello,

we connected our woocommerce via the matomo analytics and connect matomo plugins, doing some tests we realized that although visitors were tracked by deactivating the first plugin (analytics), orders were not tracked, is it necessary for both to remain active? The second problem is that not all orders are tracked anyway, there is no correspondence between the back end orders of the woocommerce and what is reported in the matomo summary, why? (out of 20 daily orders it usually tracks 1 or 2)
