I've created a meeting but its saying I'm not the host

When I create a meeting it generates links for both my non-pro account and another "addon" link which seems to be connected to my pro account. If I create a meeting and want to delete it, I'm getting Error 1100 which suggests I'm not the host. I have a recurring meeting that I want to cancel, but unfortunately the above issue is preventing this. Has anyone come across this before?
