Lilsting entered via Admin – Listing Manager only good for 30 days

I’d like to be able to add listings from Admin – Listing Manager – Add New
However, when I do so, the listing length defaults to 30 days. Even when I go in and edit the listing and try to change the listing_expiry_date it will not save. All of my memberships are 365 days.

How can I change the default expiry date when entering listing from Listing Manager.
This will also impact my ability to import number of listings via CVS import.

Thank you

Doug
