couldn't change the theme by "Configure porject" menu.
although I use theme based on implicit styles, it still cannot go to the second page to select which theme will be applied.
The "Theme button" also didn't show when you select the WPF window
I use visual studio 2017 - version 15.8.9 and windows 10.
Telerik control is 2018.3.1016
