Sharepoint list - Comments icon not displayed

[Amiryunus]

In one of my SP Online Lists, I don't see the comment icon when I bring the mouse cursor on that item. I do see the comment icon in the ribbon. The comments are enabled for this list. 

See the picture below:

In another list, I see this information. See picture below:

I've checked that the list settings are the same for both lists. 

Please help

Thanks

I have also noticed this and cannot find how to make this appear? wish comments were a specific field that showed if an item had comments and or had new comments and if you wanted to see them you could dig deeper.

I'm having the same problem... and not finding any fix online :(
