different amount of indexed document using index-esbulk or write-esbulk

After playing around with the different indexing alternatives (and changing the mapping of the latest ES Index profil) I realized that the two possibilities of writing documents into the ES index supply different amount of documents

write-esbulk: 638409
index-esbulk: 638412

At the moment I don't know why - but I think it's not a big issue for the current moment in time
