phpMyAdmin - Error > Incorrect format parameter?

I have a WordPress production website. I've exported the database by the following commands: `select database > export > custom > select all tables > select .zip compression > 'Go'` I've downloaded the file which is example.sql.zip but when I upload to my localhost I get this error: `phpMyAdmin - Error > Incorrect format parameter` I've tried to export with other formats and I get the same error. I've tried with other SQL Databases and it exports/ imports just fine. What could it be? A corrupt database or other? Thanks
