When I Click ‘Calculate’ it Shows the number after the % symbol

Hello,

I am loving this plugin but having a bit of an output issue. When I click ‘calculate match’ (https://i.imgur.com/RV0mKGc.png). It displays as ‘% MATCH TO YOU5’ (https://i.imgur.com/zMx1H9c.png) instead of you ‘5% MATCH TO YOU’.

Could you help me reverse this?
The current function appears to be in the correct order

   function hmk_get_percentage_function() {

     $user_displayed = $_POST['hmk_uid'];
     $user_logged_in = get_current_user_id();

     $hmk_match_percentage = $this->hmk_get_matching_percentage_number($user_displayed,$user_logged_in);
     if($hmk_match_percentage >=0 ) {
       echo '<span class="hmk-member-match-percent">'.round($hmk_match_percentage,2)._e('% MATCH TO YOU','bp-match').'</span>';
     }

     die;
   }

Any idea on how to resolve this? If you need a live link I will have to grant you access as you aren’t able to view the site without logging in first.

Thanks,
Kevin
