You had already added categories to those proposals and they are removed. I'm sure you can understand the pointlessness of adding categories to temporary images. From now on, try to look into history sections to see why your edits were undone.
Due to your choice of editor, every time you edit something all empty parameters on the infobox get eaten. As a result, your edit is reverted without checking what you actually edited. Please stop using VisualEditor.
