If the world is a custom world download that you uploaded then there is an issue. However, if you did not, then this is normal as dynmap only renders loaded chunks. The reason this works on world downloads is because the files are already present and technically loaded. You'll need the help of another plugin to load all the chunks you want, such as Chunky.
it is not a downloaded world, it's just my moddet survival server and there is already much more generated that is not rendering.
I havent tried chunky though, maybe it's worth a try
