Hi, Just tested Pages and Posts, and i'm getting exactly this issue also. I raised it in a seperate post a few months back.
Posts appear to save all the appropriate data so when you return to the page, the information is still in the fields. The Page Titles etc all pull through on to the site.
Pages however seem to have an issue, although when completing the SEO title and metadata and saving, the data is saved to the site pages and you can see the data in the appropriate columns in the Page list, but the fields empty of the information when you go back into the page. (they are actually empty stright after saving)
Am i making any sense! :)
I run multiple installations of wordpress with the SEO plugin, and this issue occurs on more than one of them. All sites are with the same host all using the same theme.
This particualr installation is 3.5 I'm hesistant to upgrade to 3.5.1 as the site has only just gone live and i cant afford for any major issues right now.
Although the SEO data seems to be making into the site, the plugin is not working fully as i think it was intended, at least not at the Page level.
Would love to get a resolution to this but i appreciate that with such a popular plugin, support is probably taking up quite a bit of your time!!
thanks in advance
