Alexa is wrong about date of first episode of Dutch soap GTST

As you can see here: https://www.imdb.com/title/tt0096597/episodes/, Dutch soap Goede tijden, slechte tijden (GTST) started on October 1st, 1990. However, Alexa states that GTST premiered on May 15th, 1992: https://www.imdb.com/title/tt0096597/faq/. Can a staffer look into what happened here? I fail to see how Alexa couldn't find any earlier dates, especially given the fact that hundreds of episode from before 1992 have a release date listed. (the above being said, I fail to see the point of these Alexa FAQ's because they don't give any new data, they just "recycle" data already on the site).
