Your language files are currently suffixed with “WyoDLC”. Try using “en_US” or whatever your Wordpress locale is.
If you want to keep your language files with the suffix “WyoDLC”, use this snippet in /wp-content/plugins/bp-custom.php:
define( 'BPLANG', 'WyoDLC' );
if ( file_exists( WP_LANG_DIR . '/buddypress-' . BPLANG . '.mo' ) ) {
load_textdomain( 'buddypress', WP_LANG_DIR . '/buddypress-' . BPLANG . '.mo' );
}
Also make sure to rename your languages directory back to /wp-content/languages/.
If this still doesn’t work, try regenerating your .po and .mo or post about the “weirdness” you’re experiencing.
