In a patent application, when claiming priority, how to deal with the claims in the earlier application documents that are not included in the later application documents?

If the contents of the later added claims are not written in the specification of the earlier application documents, they cannot enjoy priority, while those claims that have been written in the earlier application documents can enjoy priority.

However, if the later added claim meets other requirements of the Patent Law, such as singularity, it can be protected from the filing date of the later application.

So basically all creditor's rights can be protected, and the difference is whether they enjoy full priority or partial priority.
