That is the point. You needed those features which means that it was solving your problem of needing that functionality/feature. When people say "sell solutions and not features", it just means that whatever you sell, has to solve a problem for the client otherwise it is just a "Feature". A feature that solves a problem becomes a "solution".
If the feature was something you didn't need, you would not buy them even though the feature may be nice and shiny. So it still has to solve your problem.
