Mac Mail flagged messages are inaccurate
In Mac Mail, I constantly have 2 messages that are considered flagged with the green flag, even though when clicking on the Green Flagged inbox in the sidebar, there are no emails in that box. I just added one, and it shows up, but again, when clicking on it, it shows 1 email, but right above, it shows three in total in the inbox, but those aren't reflect.
In the screenshot, top circle shows what Mac Mail is saying how many are there. Then in the inbox, you can see that only one is actually there.
