edits to group tasks are not saved

Hi. I have created some Group tasks and I've tried to go back and edit a couple. If I click on the little pencil icon it will open up the task and let me make changes. I click "Save" and the window disappears, but the changes do not show. This includes changes to the title of the task and changes to whom it is assigned to. This happens whether it is just assigned to myself or to others. I had one of my coworkers go in and try it and they said the same thing happened to them. Is this a bug or am I missing something?

If I try to create tasks in the main Zoho Personal Tasks interface, it works fine. The problem seems to be limited to Group Tasks. Please help. Thanks.
