Which step is this occurring on? The import of structure.sql, or the import of your exported data?
I just tested the import of structure.sql without an issue, so don’t understand if that is issue.
If in the import of exported data, make sure that there is no logic to create tables. There should only be INSERT statements in that file. If it has CREATE and ALTER statements, delete them all and keep only the statements that will import data. Also when importing make sure to UNCHECK the “Enable foreign key checks” option prior to executing the import.
