The previous method of entering contacts was working fine. Easy to understand and navigate. The new "method" is, shall we say, less than ergonomic. For instance, it makes no sense to add the contacts before selecting the list. And you have the lists in the sidebar but if you select that first it creates a problem. You may have added new feature, none of which I use, you could have kept the previous more transparent system and just added them. "If it is not broke don't fix it."
