Main menu problem / Does not save the last menu item correctly

Hello,

I’m having two problems with the main custom menu of my blog.

First:
When I add a new item to the menu and click on “save” it doesn’t save the position of the menu. So I have to click on “save menu”, then change to the positions tab, choose the position and save everything again. I could live with this, the only problem ist, that in the time I need to choose the position, the menu on my blog looks catastrophic.

Second (the more important problem):
When I save the menu, it doesn’t save the last item in the menu (the one at the very bottom) correctly. No matter if I add a blog post, a site or an individual link, it always changes the last item to an individual, empty link. In most of the times it also moves this last item to the first (main) level of the navigation. So either I have a non clickable item in the main navigation, or a non clickable item in one of the sublevels of the navigation – which is really annoying.

I’ve had the first problem for a couple of weeks now, the second one seems to be new.

Maybe someone could help me?

Thank you very much!

Suzy
