my phone display shows 2 new messages but all messages have been opened

[AC Question]

the home screen text message shows 2 messages in red box which usually indicates I have received new messages but when I click on the app there are no new messages, only existing messages that have been opened.

I had this problem with my old Samsung Galaxy S3 and I resolved it with clearing Badgeprovider cache/data.
