Keyword field apparently no longer working in Advanced Title Search?

Hilariously, when you type in a Keyword in the Advanced Title Search form, it no longer gives you Keywords to choose from  Instead, it gives you a list of movie titles to click on.  If you ignore the movie titles and just leave the Keyword in the Keyword field... IMDb removes it when you run the search!  Hopefully I have explained it properly.  Anybody know what is going on?  Thanks for the help!
