Subject column icons not shown in Unified mailbox view
"Subject" column attributes (curved icons "sent" or "received") disappear from any Unified mailbox view with threaded conversations, and instead Sent messages are marked as straight arrows in "Correspondents" column. It happens on receiving a new message and auto sorting it into a conversation (threaded view). To reverse that, i had to delete "smart mailboxes" and virtualfolders.dat in Profile. TB shown curved icons in Subject column upon restart, but then changed back to straight arrow icons for sent messages in Correspondents column after getting and auto sorting new mail.

The arrows in the correspondents column are unrelated to the forward and reply arrows. But the latter to sometimes disappear if the mail server does not support those flags. Who is you mail provider?
Gmail mostly, and Forward & Reply attributes always appear for me. But the arrows in Subject and Correspondents columns appear and disappear spontaneously. At full PC reboot and TB launch, they appear. But if I close TB and restart, they disappear. Is there any setting or file to check? Why this may occur? I use TB 68.3.0 64-bit. Conversations addon is uninstalled, but it doesn't seem to affect these arrows.
Also, in threaded combo view, when received and sent messages are shown in a Unified mailbox with all threads collapsed. Is there a way to show top message of the thread in BOLD, when a new message of this thread is received and added? Currently its shown underlined, which is less visible.
try rebuilding the smart mailboxes.
