Undread submission in the inbox

We are showing we have a un-read submission on our forms but when we go to our inbox there is four there and we have viewed them all but its still showing a un read one.

I have logged out the account and back in but its still showing a un read submission.

I checked your form and you do have 4 submissions only.

Did you try clicking the Inbox to open the unread file?

Let us know how it goes.
