Doubt about removing

Hello, I am a user from Argentina. I am deleting some items from my movie collection and there are some that do not allow me to do so.
I think Listal confuses movies with tv.
These are: do not allow me to delete them or wanted or watched.

2. www.listal.com/movie/conspiracy-2001
3. www.listal.com/movie/voyage
4. www.listal.com/movie/sanctimony

I wait for an answer, thank you.

I just added and unadded some of these, so it is working for me. I did have to press f5 to reload the page as the buttons disappeared when I did so, but it took.
