StartDate and EndDate listed as not required, but no results are returned unless those parameters are included

### Type of issue

Missing information

### Feedback

I'm trying to get recovery points for a backup item, but I want to get all of them, thus I do not wish to specify a start and end date. This documentation states these parameters are not required, which appears to be true as the command will run without them, however no results are returned unless I do provide them.

Note: My recovery points are almost 1 year old. Is there is a default short range being implied that is not documented, or is this an issue with the cmdlet and/or api?
