For example:

Currently, clicking the circle (on the same line as the "(User has sent you an event line)") can't delete it, whereas the others can be easily removed. Deleting the event from the main header has deleted it, but I wonder why it (the formatting) went haywire?

Not sure whether I've created this topic in the right forum...

Is this still an issue for you?

: No. I haven't had this issue since posting this.

locking as resolved! Glad that was seemingly a one time thing.
