When the owner of a repeated booking clicks on a booking, only one instance of the booking series can be edited.

The error occurs because of this code in view_entry.php:

if($record=get_record('mrbs_entry','id',$id)) {
if(strtolower($record->create_by)==strtolower($USER->username))

}

This redirection does not include the "edit_type" parameter, and the editing therefore defaults to a single occurrence of the booking.

Proposed solution: Remove the five lines mentioned above.
