New XDP V20, testing profiled colours preview

[Luciano]

I have recently upgraded to XDP V20 perpetual after some years when I could not engage in graphical work, so my latest product was XDP X9 (I own all versions from CorelXara, Xara studio, etc. to XDP X9)
I am getting accustomed to the new interface and testing the new features.
I tested Show Profiled Colours and it works as expected, but I found out that if I choose a single separation (e.g. Show Cyan), some objects disappear in any separation view.

In the example provided the 100% CYAN rectangle in invisible in any single colour separation when the transparency effect is applied.

I tested the same file in my XDP X9 and it shows as expected.
