Why are there so many different functions in the report generation?

We are a new customer from germany and unfortunately we have complaints regarding the generation of reports. On the one hand, the quality when exporting single charts is not satisfactory. In addition, the standard reporting has different functions than the advanced reporting. In our understanding, advanced reporting should complement the standard reporting and not have less or different features.
For example, the design options of a pie chart are much more extensive in standard reporting than in advanced reporting (labeling, thickness of the circle, ...) The opposite is true for breakdown bars. Here, the options in advanced reporting are more detailed (height of the bar,...).

And please add a return button!

Please change this if possible. Since we want to create many reports, this is otherwise very tedious.
