Huawei notifcations appearing on my samsung phone

[AC Question]

My husband has a Huawei P9 and I have a Samsung S6 edge. My notification panel is showing the icons that appear on my husbands Huawei notification panel. How is this even possible? The only time our phones are kept next to each other is when they are charging. I have no idea to get rid of it. I tried switching the phone off and on but it still comes back.

Which notifications? Phone do not do any kind of sharing like that unless there is something common (like an app logged into the same account)
