Chat issue- i can't see one friend in online/offline column

Hello, I asked HDB if i should to add friend's profile. So here: (profile deleted)

Can i delete her profile link after this issue will be solved?

Thanks.

Hello, Daniel W,
ABOUT MY ISSUE AGAIN:
i dont know if you understand my message right. I had a problem that i couldnt see my friend in |ONLINE/OFFLINE| collumn after adding her. I could to see her in my friendlist.

NEW FINDINGS:
Anyway, i found her in online/offline column, Maybe i overlooked her or it just suddenly appeared there after some time. (Is visible for me as offline)


ABOUT SIMILAR ISSUE THAT HAPPENED TO ME IN PAST :
In the past with other friend did happen to me after i accepted his request, i couldnt see him in my ONLINE/OFFLINE column. He appeared there in ONLINE/OFFLINE column after some time, and i still saw him as last seen e.g. last seen month ago. (Something like this is happening again, i guess) I dont remember if i even saw him online i dont think so, but i could to see his new profile posts thats why i know that was online.

BACK TO ACTUAL ISSUE
I cant confirm if i still experience this issue I'd say yes. I see it like there are two possibilities
1) it fixed itself and she is just offline
2) or i can see her only as offline despite the fact that she is online.
I'm guessing it's going to be like the other friend as i said in ABOUT SIMILAR ISSUE THAT HAPPENED TO ME IN PAST

Thanks for your time, i hope this message is understanable.
Hopefully a solution will be found.

EDIT: Iam sure its bug, another my friend told me that she was online a while ago.
