Unwanted information in the Calendar Events

I have a slightly strange query.
So I may just be being silly, but I have two words showing up on my calendar, 'tritto' and 'surgery'. Always shown at 1:15 and 3:30 respectively, and only ever in the first column, as shown in the uploaded picture. Strangely enough, the two words don't seem to mean anything to me or my colleagues, so we can't figure out where they came from.
I appreciate the words themselves are probably specific to my database, so others probably haven't had the same problem, but I thought that maybe people have had similar problems and I was just hoping for some ideas as to why they are there and how to get rid of them. I can't see any evidence of them in any scripts, and I've taken the Layout apart trying to find them.
Thanks
