Value decimal places AUTO not working

Hi, I have a problem after updating Desktop to March 2023. The problem is setting the decimal places for the chart. The graph is controlled from a parameter so there is no direct measure. In the graph I am showing % values [0.0%;(0.0%);0.0%] and £ values [£#,## ; (£#,##) ; £#]. So the setting on the visualisation was AUTO in the place of declaring the number of decimal places but now when I want to change to AUTO it unfortunately always goes back to 1 by default. Does anyone know the reason for this. The tooltip shows the values correctly for % with one decimal place and for £ with no decimal precision
