All correct.
When you add the direct link(no folder) then JDownloader doesn't do bot handling for each link again and again but only on actual download start. when bot protection kicks in, then name is parsed from link. The package name is auto derived during linkcrawling and without correct filename, no other package name can be shown. This is all due to the bot protection. If you want we can add bot handling to linkcheck as well but that would mean adding individual links can easily lead to many captchas
