- Whole database encryption, which prevents someone from reading a local database if they gain access to your laptop.
- The option "do not send changes in local security." This refers to the local encryption settings, not to the encrypted data itself.
- Port encryption, which relates to encryption of the bits over the LAN, rather than encryption of the data on-disk. This should have no effect on the other behavior you are observing.
Here are a couple things to look for. Are you also using field-level encryption with secret keys? This could explain documents sometimes being visible and sometimes not. Check the document properties of the docs on the server. Are the fields present, but encrypted, or not there at all? Can another user see the documents that you replicate up?
