BeaverBuilder Page builder not working with Domain Mapping

Having completed the development for the site in the network, using the BeaverBuilder Page builder, I mapped the domain for the site Vale Royal Rambling Club to make it live.
Only problem is, now BeaverBuilder no longer works, unless it is set not to redirect to the mapped domain for the front-end. This leaves me with the multisite URL being displayed, rather than the mapped domain.

Logging into wp-admin as the mapped domain doesn't solve the problem either

Could you please suggest a combination of settings that will have the front-end redirect to the mapped domain, but with the BB Page builder working as expected
