MYSql - Ubuntu 20 - When importing DB, it gets duplicated in lowercase instead of writing to file
Edit server's configuration file, set lower_case_table_names parameter value in [mysqld] section to 2 (uncomment if commented, create if not exists), and restart server. See Identifier Case Sensitivity for details.
Remember, that this solution affects on all databases - but, as you show, this is the only user database on the server instance, so this method may be the best solution in your case.

Alternative solutions:
Open your WebApp3DB.sql file in some text editor and comment CREATE DATABASE and USE statements in it. Will fail if lower_case_table_names is set to zero, and database alias is added to tablenames specifications in backup queries.
Re-create the backup disabling &quot;Insert database creation command&quot; option.
