Hi,
Thanks for your query. Actually that field is dependent on the title and that's why the position field disappeared if you don't use any title. But there is a workaround for you. You can insert a space on the title field and that'll work.
Workaround is good as a temporary solution and thanks for pointing that out. What I am asking is a logical solution, what if I don't want to set a title, so you just assumed that the icon/image will always be on top of the description?
Just because the workaround works, you don't have to think of making it better. Please think about it.
