I've just described where reports are going in another comment on this post, but to expand on that, reports on the same instance are shared between community mods on the same instance and admins, which means that even though admins may see your report, a moderator resolving the report can also do this in an attempt to avoid the report being seen by an admin.

There are already discussions about improving this experience in general, but this is probably going to take at least several months to significantly improve.
