new user help needed with bell icon and pink box in admin

[cerberus]

Hi,

In the admin section their is a bell icon at the top of the page, how can I stop it from keeping popping up messages ?  I am new to Abante Cart and every time I change pages in admin a pop up appears from the bell icon, their are only a couple of messages but it keeps popping them up, I have seen them so many times now its getting annoying.

Also I am getting a large pink box when I view the brands page in admin, what is it ? and why is it there?

I have tried the search via google on this forum but it does not seem to work or produce any results

Thank you,
Steve
