dgmstuart on "Version number isn't showing up on the plugin directory page"

I'm the developer of

On the directory page (http://wordpress.org/plugins/dxw-security/) the version number isn't displayed. It should be in two places:

1. on the download button (it isn't - it just says "Download Version")
2. the default value in the compatibility section (the latest version is there in the list but isn't shown as the "current version")

I've checked everything I can think of:

• The versions are tags in svn: dxw-/security/tags
• The readme.txt has a corresponding "stable tag"
• The php file has a corresponding "Version" nimber

I'm stumped as to what I might be doing wrong. Can anyone point me in the right direction?
