Easy Blogging Plugin is not letting me add or remove menu items using the menu item add on.

We had set up this plugin with all of the menu items we needed on our test servers where we develop all of our websites. It let me add the menu items, but would not let me remove the ones I didn't want. Now we have redirected the website to it's permanent domain so I needed to recreate the menu items with the correct URLS. It let me create a few of of them, but now when I try to add more it acts like it is saving but my new menu item does not show up. It is also still not allowing me to remove menu items. It acts like it saving when I tell it to remove it but it is still in the list. Is anyone else having this issue??
