API global config change caused deletion of services from bw database

Does changing bw configuration through API override what was already configured through the UI ?
i simple PATCH request to modify blacklist data on /global_config deleted all my services and custom config.
i’m on v1.6.6
if it were not for the database backups, that would be me deleting production bw db
