The problem with Tarantino movies is that they have been 'misused' when they were released.
Kill Bill was originally scheduled for a single theatrical release, but with a running time of over four hours it was split into two parts by the Weinstein Brothers. However, it was written, shot, and edited as one big movie.
Grindhouse was also meant to be one movie, but after an unsuccessful opening weekend the movie was split into two parts. Again by the Weinstein Brothers The single parts (Death Proof and Planet Terror) that were released were extended.
Tarantino has also some credits as director in movies that are not fully his own.
Sin City has only one scene in the entire movie that is directed by him. You can view it on Youtube. This is a copy of the comic book so I can understand why they don't call this a Tarantino movie.
There is also a movie called Four Rooms. It is what they call an omnibus movie where several directors work with a specific theme, in this example the adventures of a bell boy. Tarantino's segment is only 25 minutes long so again, not a movie that is entirely his.
IMDb lists Love Birds in Bondage and My Best Friend's Birthday but they were reportedly lost in a fire according to the IMDB trivia page. However, there are some sources that say that the movies were never finished. In any way: these are not movies worth advertising since they don't exist or haven't been viewed in almost 30 years.
IMDb also lists two directing credits for CSI and for E.R. but these are episodes of television shows.
And while he was involved in the scenarios of From Dusk Till Dawn, True Romance, and Natural Born Killers, he didn't direct those movies.
