It’s very clear to see again. I am unsure if that’s a bug or not.
Doesn’t that mean that 4 of your friends have played that game in a certain time frame?
I think this tends to happen when your friends have Joins off, It may also be that It just hasn’t been updated. If my friend is playing a game It will update on the main page to say they’re playing something but if they leave It still shows the icon that they’re in the game just not the game information. (Not sure If I explained the second half very well)
But I don’t know I find the join feature with friends extremely glitchy 
Thanks for the feedback!
This refers to the number of friends you have who recently visited this experience.
We know this is confusing and are actively working on a redesign.
We appreciate your patience as we work to improve the UI.
When there is a green dot 
on the friend’s username without a title, it means that they are online but not in-experience. Is this what you are referring to?
Also, could you let us know more about the issues you’re seeing with joins? Thanks!
Thanks for your feedback - We’ll investigate and see if we can fix some of these issues.
What device do you usually use when you are using the app?
Doesn’t this mean that the user is in experience but has their joins set so you can not join them? A blue dot is used otherwise.
= Player is in a experience and they can have their joins on or customized (ie off, only followers and friends and friends).
= Means the player is online in the Roblox platform.
= The player is on the Roblox Studio.
(Just making sure everyone can understand what they mean before thinking of something else that is not accurate!)
