[Plugin: WordPress SEO] not import data from all in one seo pack and not generate xml sitemap

Hello,
I’m testing this wonderful plugin but i have some problems. Like title, when I try to import from all in one seo pack (i try too old all in one..) it speak to the import is complete, but in “titles” category i haven’t anything, only blank form.
Then I try too generate a xml sitemap but when i “click” to generate the sitemap nothing happens.
Another bug in the snippet when I edit an article in description i see the tag for gallery. (es. [gallery id=xxx] description of article description of article etc etc.)
I hope this may help for improve beta versione
Really thanks!
Simone
