Hello,

1- Under the Dashboard > Theme Settings > Custom CSS > Custom CSS for mobile area > we have applied the following Custom CSS to adjust the space between mentioned buttons:

.brush_customizer_shop_loop {
    margin-top: 0.5em !important;
}

2- As you know this Personalise button comes from a third party Plugin so we might suggest you to once try contacting the respective Plugin Support in this regard and see what they have to say about that. They can guide you better with this. Generally, when things are appearing under page builder editor and not on the Site preview, then it is mostly related to Cache being the issue. But if it is not that case, then it’s better to contact the Plugin Support.

Hope you can understand !

Best Regards.
