Bug: Show shade area for specific measure not working

Function in combo chart show shade area for specific measure not working. When using multiple measures in a combo chart (line and column chart) there is an option under Shapes, called "Shade area", when enabling this the line chart changes in an area chart which is good.
When enabling "Show" also under Shapes we get the possibility to change settings per measure, when enabled you can disable or enable the shade area for a specific measure, when I do this PowerBI automaticly changes it back.

Please fix this!!
