Fixed. See my comment at https://www.drupal.org/project/bootstrap_barrio/issues/3243148 🐛 Sub-theme Bootstrap CDN library using different versions Closed: outdated

Thank you. Setting the subtheme.libraries.yml described in #3 and disabling the bootstrap_library module fixed the dropdown issue for me. It also fixed the issue where the components/node "hide node label" checkbox had stopped working. This all worked when using the base theme but had issues when I moved to the subtheme but all good now.
