I have a pbix file which includes a MS waterfall chart visual. It presents a measure that is formatted as a percentage. All works fine. But now, the problem I have is the following: As soon as I modify the dataset by introducing a calculation item with a formatting element, the y-axis and the total segment of the waterfall visual will be presented in decimal number. The format cannot be changed anymore! That is: it will not respond to the settings in the graph, nor to the settings in the calculation item when that is applied.
NB: please mind that I do not even apply the calculation item to the visual in question, just adding it to the dataset causes this behaviour.
