Target list panels disappeared after upgrade

Hello,

After upgrading to 7.8.12(or 7.8.13) from version 7.8.3, all targets under a Target List disappear. The panels under dropdown panels(Targets, Contacts etc) that shows the Create/Select button disappears as well.

Is this a bug or do I have to press some buttons to make this come back? Have rolled back meanwhile.

Thanks,
Bobby
