Design problems with divi

Hello guys, how are you ?

I just bought the pro version of the plugin “product booster”.
And I have multiple designs problems with the divi theme (as expected).

First, the upper part of the cross sell popup is stuck behind the menu :

Then, it’s impossible to show the module on the page directly because of compatibility problems.
I’d like to test the style on the front page, still don’t know where exactly. We can try below the “add to cart” button.
Now it looks like that : https://image.noelshack.com/fichiers/2020/24/7/1592124572-capture.jpg

Finally, how to show more products than they are by default (3) for the cross sells ?
I’d like each of them to by shown together, because now any customer need to click on the next button to see the other products included in the bundle.

Thanks a lot for your attention. Soon I’ll have all your plugins in stock…
You do a great job !!
