Alerts not clearing

[hooked on smoke]

Hi all,
I'm old and sometimes a bit slow. I typically read my, "alerts", and they clear out of the list. There are several that are not doing that. I've opened and even "liked" a couple and they still show up.
Can someone help this tech challenged guy out?
I've posted a new thread and have not received any new replies.

Thanks for your patience and understanding. Im learning as I go.

Best regards.

If you have multiple alerts meaning replies to the same thread you posted they will not automatically clear.
Find the button "MARK READ" and click it after you have finished the threads.
