Hey Gabriel,
Made a temporary fix for this. I just explicitly declared the mask on the code itself.
This is located in contact-form-7-phone-mask-module/phone.php.
wp_localize_script( 'jquery-mask', '_wpcf7pm', array(
'id' => trim($id_att),
'mask' => "(999) 999-9999" /* $mask */,
'aMask' => $alternate_mask,
'reDo' => $re_do,
'reUndo' => $re_undo,
) );
