I have tried following the documentation to create a box set but first of all my application looks different to the one in the screenshots and I see much less details and none of the buttons. I have some titles which are box sets but they have no connected titles and so it's not possible to have those listed separately in my online collection like some other box sets I own. I want to contribute this edit but I currently see no way to do that.

The furthest I got was by creating empty title containers with the title of each film then trying to refer to those (by title?) when adding child titles to the parent title. However, when I click finish I get an error message "object reference not set to an instance of an object".

How can I contribute a change to an existing title or am I missing this basic feature without paying for it? I bought iOS app but maybe I need to pay more to use simple features like this in the Windows version of the app?

Previously I tried to report the missing data via the iOS app but I got an email back telling me to install the Windows application and contribute from there, so here I am :)
