Version 3.0.29

After updating to the lastest 3.0.29 version I went to my products section in the WP admin to made amendments to a particular product and filtered by category as I normally do and there were no results returned even though it tells there are products in that category. I rolled back to version 3.0.28 and the products are visible again when viewing by category. This is an issue within the products section of the WordPress admin not on the front end of the website.
