adenicol's dashboard

I am new to working with Sandy and have set up and then archived and forgot several appointments while learning my way around.

Now I have a weekly appointment for my son's soccer game, however the last game in may 17th. I went to the week after that and archived that appointment and everything after it.

In Sandy nothing shows after the 17th, however when I use ical, I get all the appointments I have archived. I even came back to Sandy and did a filter including the archived events and told her to forget about them. They still end on the 17th in Sancy but still show up in ical.

Is there anyway I can exclude these from the ical export?
