facebook - like button publish: name user liked index of/ on app name -

i have problem button: if clicked, shows on timeline post:

{name user} liked index of/ on {app name} right description , thumbnail

i set these metatag

<meta name="description" content="ho appena creato la mia storia con ''lettere d'amore'' di goldenpoint. fallo anche tu e avrai subito united nations buono sconto del 10% da utilizzare in tutti negozi goldenpoint e sullo shop on line" /> <meta property="og:image" content="<?php echo $urlthumb; ?>" /> <meta property="og:title" content="goldenpoint lettere d&#039;amore" /> <meta property="og:type" content="game" /> <meta property="og:url" content="<?php echo "https://$_server[http_host]$_server[request_uri]";?>" /> <meta property="og:site_name" content="goldenpoint lettere d&#039;amore" /> <meta property="fb:admins" content="xxxxxxxxxxxxxx" />

and button is:

<div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getelementsbytagname(s)[0]; if (d.getelementbyid(id)) return; js = d.createelement(s); js.id = id; js.src = "//connect.facebook.net/it_it/all.js#xfbml=1&appid=404791622949241"; fjs.parentnode.insertbefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> <div class="fb-like" data-href="http://apps.facebook.com/lettereamore/" data- send="false" data-layout="button_count" data-width="450" data-show-faces="true"></div>

with debugger see weird thing: if type website url, perfect, if test using url of facebook app, returns index of

how can prepare this? give thanks you
