The feature for stripping the category base will be removed in version 1.6 of WordPress SEO. We suggest using FV Top Level Categories if you insist on keeping this but do know that the feature is very error prone and not that important for your SEO.
As soon as you disable the feature below, the option will no longer be available

Please Please Please do not remove this feature from your extension :(
