Missing textdomain dw-focus

After translating DW-Focus 1.0.9  to spanish I’ve noted that some text were still untransated despite they were ok in es_ES.po. 
The problem is that this theme uses ‘dw_focus’ and ‘dw-focus’ text domains, but only ‘dw_focus’ is registered in functions.php
A simple grep -r “‘dw-focus'” wp-content/themes/dw_focus retrieve 60 matches.
Now I patched funcitions.php to register both textdomains but I suppose It should be just one. 
load_theme_textdomain( ‘dw_focus’, get_template_directory() . ‘/languages’ );
load_theme_textdomain( ‘dw-focus’, get_template_directory() . ‘/languages’ );
