Editing registrant record in unpublished event leads to removal from event

Hi Tuan,
Users have found that editing the registrant record for an unpublished event leads to the registrant being removed from that event.
This is due to the "Select Event" drop down not showing unpublished courses in the registrants profile, therefore an edit to their record leads to their removal from the event and the event id is set to 0 or null I assume.
My client often un-publishes events then re-publishes them and obviously having users removed causes a huge problem.
Can you suggest a quick code fix for this or include a fix in your next release.
Thanks

Hello

You can go to Events Booking -> Configuration, set Hide Unpublished Events From Events Dropdown config option to No and it will address the issue
