And before you say “but that’s because there are no changes between 11199 and 11201” try explaining why in that case it doesn’t offer 11198 as the latest. There are no changes between them as well.
Now to the main topic, a.k.a. numbers: note the gap between 11199 and 11201. There’s also a gap between 11193 and 11195, where 11193 is a “regular” build, and 11195 is “no changes” one. Looks like “no changes” breaks something in numbering, or at least is connected somehow to it.
