Files sitting in "Submitted Files". When do they get submitted?

I’ve ran across several unrecognized files while installing several programs. I’d look in “Unrecognized Files”, select them all, and click Submit. I usually would see a progress bar showing the files got submitted. Those files that got submitted would disappear from the “Unrecognized Files” list. They did not then go into the “Submitted Files” list. Both lists would be empty afterward perhaps because a cloud lookup found them safe. However, D+ alerted on some files for Secunia PSI and Microsoft’s Net Monitor, I selected them in the Unrecognized list, they got removed, but some were still listed under the “Submitted Files” list. It’s been a couple hours and they’re still there.

How long before those files actually get submitted?

Have they already been submitted but not yet confirmed so they sit there until days or weeks later when Comodo verifies the files as okay?

If they sit there awaiting verification, does some future update that includes them in Comodo’s whitelist then result in removing them from the “Submitted Files” list?

I’m wondering when the “Submitted Files” list gets emptied?

By the way:
Two of the files under “Submitted Files” (and originally in “Unrecognized Files”) were .log files. Really (rolls eyes)? Log files are unrecognized? I would think only executables (.exe, .com, .dll, .bat, .vbs, etc) would be considered a hazard, not text files. I would think unrecognized would apply towards something that could do something other than occupy disk space. Who cares if text, image, or other non-executable files were not in Comodo’s database. There’s no way any database could contain hash codes for every conceivable document or image file.
