Multi-site subsite theme (DIVI) modifications

Hello and thank you for checking out my problem..

Updated to WordPress 5.0 and have the most current DIVI theme applied. I can modify them theme options in the main site (schooladvice.net) with no problem but I cannot modify any theme options in any of the subsites (schooladvice.net/berlin). This is a major issue and I'm hoping the experts can help. I've granted access to the site just before writing this ticket.

Thank you
