Plugin Page not selecting the current version

Hi,

I just started with a company and have been given charge of the wordpress plugin here:

http://wordpress.org/extend/plugins/gliffy-plugin-for-wordpress/

I have updated the code, tagged it, updated my readme.txt in trunk, committed everything. Now, if you go to the page the “current version” of the plugin is not selected and the automatic updates are not seeing the plugin as having been updated. However, if you click the download button you do receive the correct current version and if you visit the download page, http://wordpress.org/extend/plugins/gliffy-plugin-for-wordpress/download/ , the correct version is identified here.

Can anyone help?
