When I have multiple files open and I switch the currently displayed in the only view, the katepartview toolbar icons disappear. It disappears one icon for each time I switch files, until there are no more katepartview icons left. Only Kate toolbar icons are left.

Here follows my katerc file to see if it helps you reproducing the problem:
