Thank you very much and please get the understanding - I DO NOT SAW my previous created theme, It is not a lie. I couldn't find it anywhere in my profile and only after making this question I did use the search within the site and found it there. After that it does appear in that different portions. In the Content and in the Overview portions. I think it might was error or something else that makes me very confused.
