Blog Categories in Safari

I have the latest version of perch and blog.

Perch: 2.6.6, PHP: 5.5.16, MySQL: mysqlnd 5.0.11-dev - 20120503 - $Id: bf9ad53b11c9a57efdb1057292d73b928b8c5c77 $, with PDO Server OS: Linux, cgi-fcgi Installed apps: content (2.6.6), assets (2.6.6), categories (2.6.6), perch_blog (4.5.2), perch_forms (1.7), perch_twitter (3.2) App runtimes: <?php include(PERCH_PATH.'/core/apps/content/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_forms/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_blog/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_twitter/runtime.php'); include(PERCH_PATH.'/addons/apps/perch_categories/runtime.php'); ?> PERCH_LOGINPATH: /perch PERCH_PATH: /homepages/32/d73729872/htdocs/millersv4/perch PERCH_CORE: /homepages/32/d73729872/htdocs/millersv4/perch/core PERCH_RESFILEPATH: /homepages/32/d73729872/htdocs/millersv4/perch/resources Image manipulation: GD PHP limits: Max upload 40M, Max POST 8M, Memory: 120M, Total max file upload: 8M Resource folder writeable: Yes HTTP_HOST: www.millersuk.co.uk DOCUMENT_ROOT: /kunden/homepages/32/d73729872/htdocs/millersv4 REQUEST_URI: /perch/core/settings/diagnostics/ SCRIPT_NAME: /perch/core/settings/diagnostics/index.php

When I go to write or edit a blog post I see that the categories are all over the place in safari. I have looked in chrome and it is fine, so no major problem and my client is using IE and have not reported any problems so it is probably ok.
