That’s the thing about debug log entries: Those aren’t meant for user readability, some might be cryptic to the point of being misleading. I still need to lookup the context of these lines in code when debugging something from time to time. In this case it just means that for that specific file only one (or no) block is being pulled at the time of the log. Just look at UI/info logging for your debugging and only consider more than that if something isn’t clear.
