Hi Chris, I can reproduce this behavior with the code you posted and it seems to be a bug. I have encountered some days ago also a problem with section handling. If you are appending a new Item to the list, while you use FullString section headers, it's creating a new section, even if it is already there. The expected behavior should be, that the new item is sorted under the right section. Especially in my intended use case, it's a problem because I want to fetch some data from an online source and sort it in different sections. But how to do that, without appending? Insert is also not possible at all, because it's varying always. Even if the model is set after, appending (again) - it's not working. Also a code example added at the bottom (just modified your code). The new person/item with name "Tom" should be displayed in Boss section, but the ListView creates another "Boss" section at the end of the list.
Maybe both are relating to each other?
Thank you very much.
Gabriel.
