Menu icons not showing

Hi,

I am having and issue with the main menu.
As you can see visiting my website, the menu works perfectly on the homepage (it shows all the icons associated to each item) but when I open it from other pages some of the icons become invisible.
Can you please check and let me know what may generated this behaviour?

Looking forward to hearing from you.
All the best,

Michael

I saw you send us the ticket, and we have solved this problem.

Yes, thank you it was solved.
I would love to know what was not working though, it may be useful for the future.

Thanks anyway.
All the best,

Michael

It involves JS downloading the font awesome set that comes with WP Bakery. Because not all page use WP Bakery, those pages will lose their font, so I added a JS to download the font awesome for the entire website http://prntscr.com/sd23fg.
