You are correct and it is the same problem on all lists in object dictionary.
It is very confusing. The intended way is to right click on the object if you want to do anything other than add.
The issue is caused by the way listview is used, the selected object is lost when focus is moved to the heading.
The fix would not be that simple and I think that my time is better spent working on the next generation gui #148, that would work natively on linux.
This issue does not exist in the new gui

Sorry to say this, but i am closing this issue as a wont-fix.
