There are a few network settings in the panel that can affect this. The value for cull distance is actually the square root of the value so its not nearly as far as one might think.
Also there is a setting I believe it’s called “update only if rendered” and “always relevant”. Some functions will need rep notify if the client falls out of network relevancy and comes back in and any values are changed. Actors can also become network dormant and become irrelevant if they aren’t “awake”.
