Customizer in Expert template Mobile view

Hi. I have been trying to use the 'customiser' with an Expert template to modify my copy of the template. When I look at the preview it is only giving me the mobile version so some of my modules which I have disabled from mobile view are not there. Is it possible to get the customiser to give a preview of a full-screen browser?

Maybe its a Browser issue!!
Which Browser do you use? And please disable any Brwoser tools if you use the Customizer.

Hi, I was using Safari 11.0.2 on a MacBook pro. I have now tried using the customiser on a Windows PC using Firefox browser and I have a full preview including the sidebar menu whereas on the MacBook I only get the mobile browser view. So yes, I guess it is something to do with the browser! I have been changing the appearance of my site's home page by using sliders (SmartSlider 3 Pro ones). What I was trying to do was to find an option to remove the white space between SmartSlider 3 modules and also the white space between the modules and the sidebar as I have ringed in yellow on the screenshot attached. I haven't been able to find a setting in the customizer which will remove it. Do you know anything about this? Maybe it's a Joomla issue and not a template one.

Hi there,
please use the Module Style blank for the slider module, because blank is removing each spaces.
Template Styles> Settings > Module

The module styles for the sliders are already set to blank.

Live url please, I need to take a look.
