Hi,
The correct configuration for JoomSEF is to disable the Language Filter plugin and enable JoomSEF's language management.
What's your other configuration in JoomSEF's configuration on Language tab? Also don't forget to purge the already created SEF URLs and clear Joomla and JoomSEF caches, so the URLs may be recreated with new configuration.
