I've recently started noticing only a certain amount of download sizes are listed in the Download queue. I've just counted 32 downloads have the correct size info but my queue is at 479 so the status bar info tip for the size of the queue is off by quite a bit! I'm not sure if this is a NBP thing or something's changed at my end?
I would've thought that given the info is in the main pane, it would re-use the file info in the queue as well?
The download list does demand loading. Meaning all the download information isn't loaded from disk until the file starts to download. I assume that's what you're seeing.
This shouldn't impact the totaled queued count though.
I paused Newsbin, added 450 things to the download list and see the status bar show the correct amount queued. I'm not sure how to reproduce it. Maybe I need to pause them all and restart and see if that impact it.
