Super, glad to hear you’ve made progress. If you’re using Ultra Premium, please let me know and we’ll shift to email. If not, sorry, I tried for ages to get email replies working with bbPress and eventually gave up.
Did you shift to the child late? If so, all Customizer settings are reset as the theme slug, the ID of the theme so to speak, changes. If that’s case, please, see this short tutorial: https://purothemes.com/customizer-settings-export-import/
