Editing node with repeat date does not update fields in subsequent instances

Thanks for your work on the module - I've used it a number of times.

I have a good calendar working well. Node in the calendar have repeat dates.

I edit a node with a repeating date, specifically the body of the node. All I want to do is change the body copy (and sometimes other fields such as the title) for all of the other repeating date nodes.

I hit save and then on the next page choose either 'update all following' or 'update all dates in the series'. It saves with no errors, yet none of the other repeating nodes are updated.

Please can you shed some light on this?

I've searched both the Date module issues as well as Calendar issues (also a google search) and have not found the same issue.

Thanks in advance.
