Hi thank you for your answer !
Currently I use the theme “Storefront ” Version : 3.7.0, and I tried to use another basic theme that is “Hello Elementor” Version : 2.3.1, and I still have this problem of “quote” buttons that do not appear, yet when I adjust in the settings not to show the button “add To card” they disappear well.
Hope you can help me to resolve that.
