Description

Repl load tries to load function if table name contains _function. Similarly for the below contants

public static final String FUNCTIONS_ROOT_DIR_NAME = "_functions";

The code just checks for contains(FUNCTIONS_ROOT_DIR_NAME). So even if any table or db name contains _functions, it takes the Function Load flow and fails.
