[Koha] Bug: memberentry.pl Does Not Auto-calc Expiry and Joining Date

Hi, While transferring our membership database I noticed that memberentry.pl does not save Joining date (leave blank for today): Expiry date (leave blank for auto calc): I've loaded our dates by importing the member data into MySql from a CSV file. However when adding member manually the dates are not auto-calced as seems to be intended by design. Perhaps I've overlooked something, but if this is indeed a bug I'll be happy to add it Bugzilla. Natuarally I'm secretly hoping for someone to provide me with a quick magical fix and then claim the swooning credit from our head librarian. But then life usually isn't like that :-) TIA Bo
