Missing titles in upcoming movie list

When looking at the upcoming movie list for Germany (https://www.imdb.com/calendar/?region=de), I noticed that some upcoming movies are missing on that list. For example, "Avatar: The Way of Water" and "Operation Fortune: Ruse de guerre" are not included, despite both having a release date listed on their respective IMDb film listings for Germany. This issue is also true for other countries, for example Avatar in Australia (https://www.imdb.com/calendar/?region=au). Interestingly, Avatar IS listed on the US movie list (https://www.imdb.com/calendar/?region=us).

Can somebody from the technical staff have a look at this?
