Global tables created not used by sub-blog

I have installed bad behavior and login lockdowns. A global table is created but the sub-blogs do not use the global table when i network activate them. I have to activate them one by one and if i do that, tables will be created for each sub-blogs.

Apart from having to manually key in all the settings for new sub-blogs, it will also be very difficult to manage the logs.

I checked the codes of both plugins and they seem to use the global database. so am not sure what i have done wrong. pls help
