WP2Static and WPML

Hello, I’m using WPML to have another language (/DE) in my site
but on the static site it’s giving me error 404

i saw on Detected URLs that it’s not showing me the DE folder.

I saw this ticket
https://www.ads-software.com/support/topic/wp2static-and-wpml/
but it’s not working for me

i’m using Version 7.1.6

Please help

Thanks
