Trouble keeping deleted messages in the inbox index

I set Server Settings to "Just mark it as deleted" when I delete a message. But after a minute, it disappears from the Inbox. This started right after a Win 10 reinstall. Using IMAP.

Thank you, christ1, for this answer. However, I use Thunderbird, not Postbox. Still looking for an answer.

Postbox is based on Thunderbird.

thank you both! Seems to work now.
