Theme and layout colors overwriting custom colors in pie chart

Hi,

When a Pie Chart is set to “Colour by: Single Colour” then Theme and Layout Data Styles Chart Palette (the first colour) overwrites custom coloring right after switching from SET-UP to STYLE tab in Properties bar. Basically, when clicking on STYLE, colour changes, which seems like a bug.

According to the documentation that should not happen and custom colours should overwrite predefined style when set up.

Is there a way to fix this? It is hard to control all possible changes on dashboards and defining a theme and layout consistent set up is not an option right now for me.

Kind regards,
TS
