3rd column not showing up

Hi all,

I'm using divi to assist a client in the development of the site. on the following page https://realdev.co.za/barnlab/products/beef/ the 3rd column isnt showing up when I exit the divi builder, but when I edit with the builder it shows up.

Wordpress V 5.5
Divi V 4.5.6

The cache plugin was used to clean all cache on the site still nothing and I've disabled the plugin as well same issue.

Config memory is set to 256mb still nothing

When I use Firefox development tools its not even picking up the 3rd column. I've even switched to a 2 column section and that pushes the 3rd column out but then the 2nd one is gone.

 

1st out divi builder
2nd in divi builder

 

All is fine in the divi system check
