Certain agendas not accessible (corrupted?)

Two of our agendas won't load and I can't find a way to edit or even delete them.
Something similar happened about a month ago and I was informed that one of our agendas was corrupted. I don't know how that happened but the solution was to remove it from the backend. Since then it's been working fine.

Until now.
This time, the following agendas will not load:  635.toastmastersclubs.org/agenda-01960462.html and  635.toastmastersclubs.org/agenda-01960463.html . The only edits I'm aware of since these agendas were created, was to mark one of our members as "not attending."

If we are doing something incorrectly, please educate me
For now, can you please delete the above mentioned agendas for me?
Thanks!
