Why are are certain messages in my Apple Mail app are highlighted in light blue in the the Message List as shown in the attached print screen?
As I recall, I never noticed this before until now. Organize By Thread is disabled, Conversation Views are also disabled.
For example, If I select a email message with the same Message Thread as you can see from the image, the rest of the messages with the same email Sender are automatically marked as a lighter blue.
Same goes for the Sent items folder as well. Not only just the Inbox.
The rest of my messages seem to be acting normally.
