What is an elsan? Sorry for my poor English! No, I did everything by the book I will give it a try

Hi all! I bought one of these for my boat and camping life. https://www.thetford-europe.com/au/product/porta-potti-qube-365/ I was wondering if any of you can give me advice on how to clean this thing? We used it for one day where my 6 years old made a huge poop in it and then we used it for peeing. In the evening I followed the instructions on how to clean it. First I emptyed the wasteholding tank and then filled some water/chemicals and shook it and then emptyed again. My issue is that there is still some feces in there. I have tried cleaning it again two days later, but it's like stuck on the wall or something inside the wasteholding tank. Is that normal?
