Probably the data that you needed was fine! I had a chat with a member here about the Belgian lotto. He had the data from LP and I tell you that it wasn't correct.
We have sometimes extra drawings, the games changed in size and in payout. For keno we used to have a 20/80 and now we have a 20/70. Different games shouldn't be in the same database. So, basically the job wasn't well done. I don't know if you can download Keno, pick3, lotto, super lotto, extra lotto, joker and joker+ for Belgium in LP. That would be a good job. Also can you filter in that by days?
I don't say that they don't work. I also heard about mistakes in databases for other lotteries. Sometimes you don't find the game in the set of databases. A+ from GH has the same problem. Checking out other open programs per country, I also found mistakes.
I get the results straight from the local lottery online, and I also can get the count of winners with the amount of payout in another file.
When I saw mistakes with the Belgian website, I contacted them, and I can tell you that they do something. The online site for playing has just been renewed today.
