Hi elmechu,
The translation files should be fixed now. If they are not, please let me know.
In regards to changing the slug from ‘announcement’ to your language, you can do so using the filter defined in the plugin, ‘timeline-express-slug’.
Example:
// alter '/announcement/' to be '/event/'
function timeline_express_change_announcement_slug( $slug ) {
$slug = 'event';
return $slug;
}
add_filter('timeline-express-slug', 'timeline_express_change_announcement_slug' );
You’ll need to add that to your functions.php file of your active theme. If you are not sure how to do that, you can use a third party plugin to achieve it. My Custom Functions works well.
Once added, you’ll want to refresh your permalinks by heading into ‘Settings > Permalinks’ and clicking ‘Save’.
Update: I also just put together this Documentation article which outlines the process as well:

Thanks!
