Note: I have deleted the Divi cache and browser cache.
I am currently building a new website on WordPress with Divi builder.
I have attached 2 images. The first image shows 3 slides (desktop). You can see the navigation arrows left and right.
The second shows 4 slides. As soon as I change the number of slides from 3 to 4 the navigation arrows disappear on both sides.
I have deleted the Divi cache and browser cache which made no difference
