Messaging bug

I started a conversation using the menu button on a friends profile, which gives a small window.

I then later added to the conversation, but when I go into the menu on my own profile page, on the left, I can't find the conversation. If I send my friend a new message, then the thread of messages shows up. 

but no conversation in my archive....

...now I send a new message...

Carefully look at the time stamps and message trail of the pics and you'll see the glitch. Thanks in advance for your time and effort. 

nothing happened with me yet

Thanks! I'll have a look; we do have new messaging coming soon  

I saw the new layout for the messaging thing. I thought it was a bug for a second  Some of the messages are displayed as unread even after you've clicked on them in the new messaging thing.

THanks we've got a ticket for that to fix! 

Worse for me. It does not open the msg even when I click on them but I am using website through mobile now
